If there is no Logs folder, that is a very important clue. It means the program is crashing
instantly—before it can even write a single line of text.
This almost always means one of two things:
1.
The Registry Path is wrong (Windows cannot find the files to start the engine).
2.
The files are "Blocked" by Windows Security.
Please check these two things carefully. Do not skip them, as this is almost certainly where the problem lies.
1. The "Folder-in-a-Folder" Trap
This is the #1 cause of "No Logs."
When you extracted the files, did it create a folder inside a folder?
- Wrong:
C:\ISTA\ISTA\TesterGUI
- Correct:
C:\ISTA\TesterGUI
Check this now:
1. Open your ISTA folder.
2. Do you see a folder named
TesterGUI right there?
3. Or do you have to click into another folder to find it?
The Fix:
The path you put in the Registry (
InstallLocation) must point to the folder that
contains the
TesterGUI folder.
- If your
TesterGUI folder is inside C:\Users\Name\Desktop\ISTA, then your Registry key MUST be C:\Users\Name\Desktop\ISTA.
- If your Registry key says
C:\ISTA, you MUST move all your files to C:\ISTA.
2. Unblock the Files (Critical)
If Windows thinks the files are "downloaded from the internet" (which they are), it will silently kill the process instantly.
1. Open your ISTA folder.
2. Find
ISTAGUI.exe.
3. Right-click ->
Properties.
4. Look at the very bottom of the General tab.
5. Do you see a checkbox or button that says
Unblock?
*
YES: Check it, hit Apply, then OK.
*
NO: It is already unblocked.
3. Run as Admin
Always right-click
ISTAGUI.exe and select
Run as Administrator.
Check the folder structure vs. the registry key one more time. If they don't match 100%, it will never start.
