somehow my installation on win10 canceled during finish. "Installation of Caché finished" showed up for 20 minutes and canceled with an error I didn't saved.
Every file and service was installed but never registered as successfull installation. Now I try to reinstall it but the installer shows me everytime "Another installation is already in progress. Please finish the second installation first".
The unfinished installation is broken. I can't startup Caché from launcher. So I deleted everything in c:/intersystems
Things I already tried:
- Removing all Temp-Files with the cleaning tool from Windows (also "Clear Systemfiles")
- Remove from "Programs" list (it's not there due to unfinished installation)
- Restart Computer
- Searching registry for LOCAL_MACHINE/Microsoft/Installer/InProgress (not found)
- Searching registry for LOCAL_MACHINE/Microsoft/Current Version/Installer/InProgress (not found)
- Searching filesystem for temporary Installation-Files from ISC (none found)
- Searching registry for ISC entries (only non necessary keys found like "last searched terms", and entries for the services like CacheHTTP)
- C:/Intersystems- Folder is not present (my installation directory I deleted earlier)
- No Process of "Windows Installer" is running
- sfc /scannow -> no Results
Where is the flag located that an installation is already in progress?
I can't even install another instance with that problem.
Got the error :
Product: CACHE-- Error 1719. Windows Installer Service could not be accessed.
The Windows Installer Service is active
I don't know
There was a msiexec.exe in my process list (also after restart).
I killed it and now I can install but now the next problem arrives (installation started with admin-rights):
Installation will not finish, Caché-Launcher is not in Task-Bar.
It cancels again with "Windows Installer Service not available".
Trying to reinstall the instance gives me "This action is only available for products that are already active"
Wierd problem. Something in Windows wants to f+++ me up. I post a solution as soon as I have one
