Can't reinstall or uninstall Acronis Backup 11.5 Server Essentials
So two nights ago I downloaded and installed (attempted tp install) the 43994 build of 11.5 on our server. It kept erroring out on the Agent Core install with the following error:
Code: 06442537
Line tag: 0x394351065f8e4b20
Message: Installation error.
Suberror
Code: 01603
Line tag: 0xbd28fdbd64edb8ee
Message: Fatal error during installation
After doing a server restart the install started giving me the option of Update, Modify or Uninstall. When I try to uninstall it fails on Agent Core, same happens if I try to modify or update as well. I goto Program and Features to uninstall, it isnt there. I ran Revo to uninstall and uninstalled both Acronis items it found. Ran a registry cleaner and marked all acronis entries it found to be deleted. Then restarted the server but the options were still the same on the installer. Now its not listed in Revo, the reg cleaner didnt find anything. No Acronis Files in Program Files, Program Files (x86), Program Files
Common, or in Program Data. I ran the Acronis cleaner and it said there was nothing to do. Tried the FixIt tool from MS but it didnt work either. The log file attached is from the install.

Hello,
Sorry for the late reply.
According to the log, the installation fails when detecting the Acronis Management Machine service (mms) user. Could you please check the services for this? You can do this by running the command
sc query mms
If the service is there, please try to delete it (and other Acronis services). If it is pending delete or something like, Windows probably requires a reboot.
