Installer Service won't run - error 997
Posted on 2005-05-07
I'm having a problem with an XP SP-1 machine that had a spyware attack and seemingly a failed installtion of antivirus software.
The Windows Installer service is broken, and I cannot install any setup programs that rely on it. For example, Acrobat Reader 7 says it cannot connect to the Installer Service.
When I go to the Services control panel and attempt to start the Windows Installer service, it cannot start. I receive Error 997: Overlapped I/O Operation in Progress.
I have double chaecked that the spyware (eager-search trojan) is gone. I have terminated all processes not essetnial to running the machine, and have even tried stopping non-essential services. Nothing I can do will get teh Installer Service to start.
The user account is a member of Administrators. I checked that as well. This is a standard business workstation - no web server software, no database software, etc. - just MS office and a few other misc. apps.
Any ideas what might be causing this? I'm stumped and googling the error has been no help.
