I have 2015 - 2022 x86 and x64
Since you have the C++ runtimes installed and the paths match, we are dealing with a "silent death" of the application.
Please do this exact test. It is the only way to see the error message that is being hidden from you.
The CMD Launch Test
We need to run ISTA from the command line to force it to print the error code.
1. Open your ISTA folder where ISTAGUI.exe is located.
2. Click the address bar at the top, type cmd, and hit Enter.
3. In the black window, type:
Code:
ISTAGUI.exe
What happens?
- Does it say "Bad Image Format"? (This means a DLL is corrupt/wrong version).
- Does it say "Unhandled Exception"? (This is a .NET error).
- Does it say nothing and just give you a new line?
If it says nothing:
Run this PowerShell command to force-unblock every single file in the folder (sometimes unblocking just the EXE isn't enough).
1. Right-click the Start button -> Windows PowerShell (Admin).
2. Paste this command and hit Enter:
Code:
Get-ChildItem -Path "C:\ISTA" -Recurse | Unblock-File
Please report back with what the black CMD window says.
