If the TurboTax App won't open, you can temporarily turn off your antivirus or firewall.
If it still doesn't work, reinstall the app using a new installer or fix your Microsoft Visual.
In case you are still having the situation, follow the instructions given in the link below:
Uninstalling TurboTax and then uninstalling Microsoft Visual C++, then reinstalling TurboTax fixed my issue
Thank you so much for sharing what worked for you because it worked for me too! There were several versions of Microsoft C++ installed. As suggested, I uninstalled all Microsoft C++, uninstalled Turbotax 2025, restarted device. I reinstalled Turbotax 2025 which installed Microsoft Visual C++ 2015-2022 Redistributable (x64) - 14.44.35211. Turbotax 2025 successfully launched and even ran updates.
TurboTax 2025 was the 3rd app that failed to launch within the past few days. Adobe Acrobat Reader DC quit working a few days ago, saying that msvcp140.dll could not be found. Acrobat Photoshop Elements has the same problem. Web chatter on the Acrobat Reader issue exists, but it is not consistent, so I have not attempted a fix, yet. Microsoft Visual C++ is mentioned by a few people.
I just now tried to launch TurboTax 2025 Home and Business from the app tray, and nothing happened...same when trying to open my tax file. I have a relatively new Surface Pro 11 (ARM), and Visual C++ has six installed versions (2012x64, 2021x86, 2013x64,2013x86, 2015-2022x64,2015-2022Arm64).
Would you suggest uninstalling TurboTax 2025 and all of the Visual C++ versions? Should I also uninstall older versions of TurboTax before reinstalling 2025? Any guess on whether this will cure Acrobat Reader and Photoshop Elements? Thanks!
Looks like I have THREE Microsoft C++ apps:
Microsoft Visual C++ 2010 x86 Redistributable - 10.0.30319 (dated 3/26/2024)
Microsoft Visual C++ 2015-2022 x86 Redistributable (X64) - 14.44.35211 (dated 2/8/2026)
Microsoft Visual C++ 2015-2022 x86 Redistributable (X86) - 14.44.35211 (dated 2/8/2026)
I'm suspecting the last two because they're the closest to the most recent Microsoft system update. Three weeks ago I opened last year's TurboTax to grab a document and now I can't even open that version of TT.
Do I get rid of all 3 MS Visual C++ apps?
I had the same questions you have. I can't say whether it will help your Adobe apps but yes, deleting all versions of MS C++, uninstalling all versions of Turbo Tax, rebooting, exiting my VPN (which may not have been necessary) and then installing Turbo Tax WORKED!.
