Install Error 1402. Could not open key: fails for office 2010, HP 5590 sw, and VMware

Error 1402. Could not open key: UNKNOWN\Components\2A31EAB9FA7E3C6D0AF18C3B9B1A1EE8\2BC5FF3A53BF85647815E9EDD1563BAASystem:


Vista 64, has worked fine for years.
Had a problem w/ my HP scanner and based on tech support directions, I directly edit the registry and since then the installing/uninstall applications have been hosed.

Specifically the following fail:
office 2010
Vmware 7 uninstall
Vmware 9 install
HP Scanjet 5590 un/install

All research seems to point to ACL issue with registry, and I am afraid I have irreparably hosed the registry

I have tried all of the following:

http://www.okino.com/conv/changing_windows_registry_permissions.htm
secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose
http://blogs.msdn.com/b/astebner/archive/2006/09/04/739820.aspx (Solving setup errors by using the SubInACL tool to repair file and registry permissions)

and it seems at least a dozen others.

I have tried fixit and windows install cleanup (but not http://msdn.microsoft.com/en-us/library/aa370523%28v=vs.85%29.aspx as the GUID doesn't exist in registry)

Any suggestions beyond those above? Am I hosed and just need to do a clean Vista install?

I install and uninstall s'ware frequently so I don't know how well the system restore point would work.

Sounds like you have identified your two options correctly. Personally once I decided that a clean install is required I would first try a system restore point as you have nothing to lose at this point and plenty of time to gain.

Best of Luck

Some bright person (me?!?!) turned of system restore/VSS, so the only restore point I have is from today.

The good news is, I have seen several posts that a clean install will help performance.

Thanks.

Absolutely, this is especially true since you noted you install and uninstall a lot or programs
