I had similar problem some time back , make sure you using latest WinRAR or 7zip after I updated no problem @ all as well makes sure after unpack read only is unckecked for all sqlitedb files

I try every solution to fix the database connection error.

1. Try to unblock files manual. - doesn't work.
2. Try to unblock all files in Rheingold folder with Powershell als administrator and the following script "gci ’C:\Rheingold’ -Recurse | Unblock-File - doesn't work.
3. Try to use latest 7zip - doesn't work.
4. Try to start ISTA as administrator - doesn't work.
5. Try to clean registry with RCleaner 4.4 - doesn't work.

Anyone has an idea?

PS: Has anyone the hashvalues for the sqldbs to compare them?

Did you try winar? Did you check prerequisite software?

before i try it with 7zip i use winrar.

The previous version of ista-d works perfect.

You have these lines in registry?:

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\BMWGroup\ISPI\ISTA]
"DataVersion"="4.08.20"
"DataVersion_en-GB"="4.08.20"

You have SDP data installed or use without SDP data? If you don't instal SDP:

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\BMWGroup\ISPI\Rheingold]
"BMW.Rheingold.Programming.ExpertMode"="False"
"BMW.Rheingold.Programming.Enabled"="False"

Have you installed same languages as before?
For Example on old Rheingold use Dutch language but in new one not available. Maybee old user registery stil on dutch and the program try to start with dutch database

Yes. Look here.

Looks like it is displaying correctly, but that error can still be due to registry error or missing prerequisite software.
