How to Install TurboTax Deluxe 2020 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.

Now use radare as follows:

Command	Description
r2 -A -w "setup - copy.exe"	analyze and allow writing
axt str.Detected_OS_is_WIN_8_or_above	look for references to this string
s 0x402ec2	seek to the location that was found in the previous command
VV	now we are at the node references the string. You need to reverse the opcode in the previous node by changing je 0x402ed9 to jnz 0x402ed9
Shift-TAB	go to previous node
(	reverse the opcode
qq	exit from visual mode
q	quit radare

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

This is a much shorter/faster way that only needs a hexeditor.

Open the setup.exe file and at offset 0x000022c0 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.

Thanks for the info. I don't have Ghidra or java runtimes installed to run it, but I did find and changed
the disassembled code with a simple hex editor:

Sorry, but I'm still getting the "OS doesn't meet minimum requirements" dialog. I tried NOP'ing some nearby jumps too, but still not working.

Note that this computer has never had TurboTax installed, so perhaps your setup is doing something differently if TurboTax has already been installed.

Whoops, sorry. I originally ran it using a slightly different, more complicated modification, but decided to (incorrectly) simplify it when I went back and wrote it up. Try using eb 32 (JMP +0x32) instead of 66 90 (NOP). I'll edit the original post as well to remove the incorrect info.

Thank you, that was it! It went straight to the installer this time.

CORRECTION:
e8b8e8ffff85c07432 (orig)
e8b8e8ffff85c0EB32 (edit)

Tax preparation software shouldn't need the latest and greatest operating system to run in any universe.
Thanks again.

I could not figure this out. an easier tutorial please? can we get this done for "TurboTax_Individual_2021_PC.exe" ?

Well, the 2021 setup installer worked great, and all was going smooth until I tried to install a state-
The state installation will not stick.
The MSI is woriperStateIS.msi
Not able to upload it here.

IS there a fix for the state?

Whoops, sorry. I originally ran it using a slightly different, more complicated modification, but decided to (incorrectly) simplify it when I went back and wrote it up. Try using eb 32 (JMP +0x32) instead of 66 90 (NOP). I'll edit the original post as well to remove the incorrect info.

I'm interested to know about this as well - the initial mod works great for the main TT installation but state won't install. Any advice is much appreciated!

This is what I see too. The state seems to install.

1. I hit "Start" next to Virginia, and I see this:
   

2. I hit "OK", and see this
   

3. I hit OK and see "Getting your state". I allow the program to make changes and see this:
   

But when I hit "Continue using Turbo Tax", nothing changes. Selecting "Start" next to Virginia just sends me around the same loop.

Thx Scorpius
This fix was to be able to run Turbotax on Windows 7. the state issue is another problem not related to this. try downloading state without entering info for federal and see if it downloads that way. I got it to work that way. check your forms folder for your state forms if it downloaded.
