Recently I posted a problem I encountered which originally I thought was caused by a regresssion in SP04 of SW2011, but which was probably caused by an installation error stemming from an error code 1402 (Registry corruption). I found a solution for MY problem and I thought to share it here. The Installation Manager error I was encountering probably first reared its head while installing SolidWorks 2009, or possibly in deinstalling it while installing SW2011 on top of it. The problem first manifests itself thusly:
This seems to have been caused by a Permissions problem with one or more specific keys in the Registry (resulting from Registry corruption). After finding the problem key identified in the Installation Manager error above (using Regedit) I could not delete it and I could not change Permissions manually (Windows Vista). I found a solution to resetting the Permissions globally for the Registry on another Web site. There is an obscure but very powerful Windows utility named secedit with the / configure switch, which can do this (and more, if you're not careful). AS AN ADMINISTRATOR and from the Run command line:
secedit /configure /cfg C:\Windows\inf\defltbase.inf /db defltbase.sdb /areas REGKEYS
This resets the Permissions for only the Registry (this is what the last argument "REGKEYS" effects). Note this is a potentially dangerous fix and should only be attempted when all else has failed. And your mileage may vary.
