How to Install TurboTax Deluxe 2021 in Windows 7

Run the TurboTax installer until the error dialog pops up. Click the close button since you can't go any further. Now press WinKey-R and type %TEMP% to go to the temporary folder. Copy the ckz_XXXX folder to the desktop. Select the Setup.exe file and press CTRL-C then CTRL-V to make a copy/backup.

Now use radare as follows:

Command	Description
r2 -A -w SetUp.exe	analyze and allow writing (thanks to @SureshotM6)
axt str.CurrentVersion	look for references to this string
s fcn.0041cc60	seek to the function's location that was found in the previous command
VV	Use visual mode
p	optionally show addresses
x	jump to xref
l	seek to ref/xref
(	reverse the opcode
qq	exit from visual mode
q	quit radare

Now you can click on "Setup.exe" and install without error. (Note that the Verified publisher says "unknown" even though we only changed one byte.)

This is a shorter/faster way that uses powershell to change one byte.

Paste these commands into a regular terminal window:

cd %TEMP%
cd ckz_XXXX
powershell

Now paste these command into a powershell window:

$bytes = [System.IO.File]::ReadAllBytes("Setup.exe")  
$offset = 120746
$bytes[$offset] = 0x75
[System.IO.File]::WriteAllBytes("Setup.exe", $bytes)
exit

This is another way that only needs a hexeditor.

Open the Setup.exe file and at offset 0x0001d7aa change the 74 to 75. Save it and you are done. Remember this offset only works with the version of TurboTax Deluxe mentioned above. If you have another version, follow the radare instructions above to find the right offset.

DISCLAIMER: This is for educational purposes only. Use TurboTax in Windows 7 at you own risk. It most likely will work just fine, but Intuit doesn't want to support older versions of Windows.

I ran into the same "infinite loop" issue. Several other "taxpayers" have experienced this problem, as posted on the last-year version of this page at gist.github.com/scorpius/b19023b74754bd8f55da067070d67ed5

I spent several hours trying to resolve "this loop" because hundreds of others have experienced this very problem on currently supported Windows OS versions, as well. None of the fixes worked, however. Since time was running out, I had to install TurboTax on a Windows 10 to successfully download and install the state return, complete, and efile my returns just before the deadline!

As a result, I think that another OS "check point" is probably baked into the TT installer or its .msi counterpart! We need to research this issue further, preferably with brandonwu and Scorpius leading the way! I have to tackle my backlog now since I spent too much time on my tax returns this year!

If you have not finished your returns yet, please get them done and mail hard copies to IRS and the appropriate state agency ASAP. They usually face such a deluge of returns that they normally ignore a few days of delay. If you cannot finish them soon, just file for extension and pay them a bit more than your estimated taxes due! You will then have until October 15, 2022 to complete and file your tax returns.

Good Luck!

Thanks for your reply. I just went through the thread from last year that you linked to. Yes, it's the exact same problem I encountered.

I was in the same boat as you. I spent hours on it including 2 of the fixes recommended by TT here. I got nowhere with that so I ultimately had to finish the return using a drive with Win 8.1. I did not try the final recommendation of starting windows with selective startup and running the TTStateCleanup at that point. Maybe that will work. I'll give it a shot and report back.

Also, a user at the end of the thread that you linked to said he had success if he downloaded the state before entering any federal info. I attempted to do that after uninstalling then reinstalling TT. However, during the installation, TT downloaded the state automatically. Clearly it knew which state from the previous installation. It appears that the uninstaller is not very thorough. Is there a way to COMPLETELY remove TT?

Thanks

I am impressed that you came up with essentially the same workaround that I used to file your returns, and that you continue your efforts to resolve this issue. Just to save you some time, however, I decided to add that...

I tried most, if not all, recommended TurboTax community solutions, including those you listed such as TTCleanStates.exe and "selective startup", without success. I even managed to manually download the "State return", with the superb assistance of a TurboTax associate who went the extra mile to let me get this download. I then tried every possible way that I could think of to manually install this update only to get a 2803 error, no matter what! This installation error is rather common, as well. In short, I have not found any resolution for our issue yet! Thus, as I stated in my previous post:

"I think that another OS "check point" is probably baked into the TT installer or its .msi counterpart! We need to research this issue further, preferably with brandonwu and Scorpius leading the way!"

Thank you, again for your "resilient efforts". I hope we can come up with a fix for this problem before the next tax-return season arrives!

Changed the one bit in Hex editor and save the file to a new name Works So simple

I still use Windows 7, and like I said before, tax preparation software doesn't need the latest and greatest operating system. That is a joke in itself.
Here's a Hex Editor solution for TurboTax 2022, setup.exe file:

E8FFFFE8D8E8FFFF85C07432 (search pattern)
E8FFFFE8D8E8FFFF85C0EB32 (replace)

Thanks for this. Worked like a charm. I agree that it is a joke to restrict paying customers for no reason. They must get a kickback from MS.

For folks trying to make states install on Windows 7 - the state installer .msi also needs a quick edit to change the OS check.

first, you'll need the Inst Editor: http://www.instedit.com/ - download that, the free version is fine, and install that.

second, you'll need to grab the State MSI. For me it was in:
C:\ProgramData\Intuit\Common\Update Service\v4\Data\e02ec8e6200f4bf9af32572fea31f457\C\C-wcaiperStateIS\022.000.0115_msi\v1\F\wcaiperStateIS.msi

(note that the "CA" in the file name "wcaiper" refers to the state abbreviation, so if you're elsewhere, the name will be different)

Open your state .msi with InstEd

In the Tables tab, find Launch Condition:

Double Click on VersionNT>=603 and change it to VersionNT>=601

Save the .msi, run the .msi - and you'll get install dialogues, etc.

I am impressed that all three of you have managed to install TurboTax on a Windows 7 machine. swinokur's solution is quite simple and elegant. Had I known this a couple of weeks ago, I would have probably kept my Windows 7 Home Premium OS!

However, I could not resolve the State return issue last year and had to resort to a Windows 10 machine to complete it. Further, many software vendors, including security providers, are no longer supporting Windows 7. As a result, I decided to upgrade my OS to Windows 10 this year, even though my laptop manufacturer's "Tech Support" gurus claimed that it was not "upgradable" at all, by managing to:

1. Find two expensive 4GB DDR2 RAM cards and upgraded the laptop to 8 GB of RAM.
2. Download Windows-10 ISO file, backed up all my data, and recorded all installed apps and settings.
3. Update Windows 7 to the latest Service Pack 1.
4. Install Windows 10 Home and selected to keep all my data and apps!

The entire process took many hours to complete, but the results are impressive. My laptop has a new life, is quite fast now, and installing TurboTax 2022 was quite simple and fast!

This might be too late for most of you this year. But, I recommend that you all consider this alternative for your 2023 returns. Meanwhile, I wish you all fast tax-returns filing and sizable refunds!

Good luck!

Hi there,

With the 2022 "Home & Business" version I'm not finding in the SetUp.exe file E8FFFFE8D8E8FFFF85C07432, and the value I see at offset 0x0001d7aa is FE (instead of 74). Also, although running the "axt str.CurrentVersion" command returns "fcn.0041cc60 0x41cca0 [DATA:r--] push str.CurrentVersion", with a Hex Editor I can't find an offset value of 0041cc60 (the offset goes up to only 001507DF).

I'm starting to wonder if I'm totally clueless :)

This works for TurboTax Premiere 2022. Perhaps the setup.exe is different than Home & Business 2022.

Has anyone figured this out in 2024 for TurboTax 2023?

I haven't purchased TT this year, but if I did, it would be TurboTax Premiere.

If I want do my taxes on Windows 7, then that's my choice. If they refuse to let you to do taxes on the operating system of your choice,
then you're left with some alternatives (without changing your operating system):

• Do it online. No software required, just a browser. Some people may not want to give Intuit access to their tax data, as it will be stored on their servers, for who knows how long. Is there a way to get them to delete your information after submitting it, I don't know. Or even worse, they may try to share your tax data, or sell it without your permission.

• Switch tax software companies, like H&R block. I read H&R block was more friendly with older systems (they only give a warning, and not block it completely like Intuit), but that may have changed this year. Must be verified.

• Patch it with a hex editor.

Right on. Looking for the patch for TurboTax Deluxe, the exact offset and location. The posts here have worked beautifully for the past three years. Appreciate these efforts. No reason why we can't use Windows 7. Thanks for the comment.

OK. I'm no great expert like the folks who worked all this out - so I can't provide foolproof radare2 instructions. However - a hex editor and trial and error worked for me. I searched for 85C07432 in setup.exe of TurboTax 2023 deluxe in a hexeditor. This pattern occurred four times in my setup.exe. Change the second instance to 85C0EB32. This pattern starts at offset 000178fb and the '74' which needs changing to 'eb' is therefore at offset 000178fd And Bob's your uncle.

PS I imagine there is more work to do to fix state taxes - but I just did those manually last year - it didn't take long because State is much simpler than Federal.

UPDATE Well maybe I spoke too soon. This allowed me to complete installation, but I am getting an error when actually running the program - so maybe more is required :-(

Same here. Almost worked! I'm still trying various options, uninstalling and reinstalling it. I'm overseas and have a 2-month extensions...so a little more time to figure it out. Thanks for getting this far.
