Let me know if you don't make any progress soon and we can go from there.

Ran install as administrator and did not work.  i will keep fusing with it.

Well, the install actually calls the gacutil /f command on the assemblies.  So it would seem, like you said, to be a permissions issue.  Can you right-click the intsall and then click Run As Administrator?  I would be curious to see if you have the same results.  Also, jsut for grins, do you have a laptop or another machine that you can load on just for comparision and as a test?

Ok - deleted files from GAC and reran install-> now, no files in the GAC.  any other suggestions?  i know this is a permissions issue just don't know exactly what.  my login is in the administrators group.

This is probably a good indication of what happened during the install.  It looks as though it were probably a permissions issue.  Let me know if you don't get this resolved.

Hi Mike,

In Vista, you must be part of the Administrators group in order to remove files form GAC.  Simply select all the MicroFour*.* files and hit Delete key.

Ok..a little rusty with VISTA - how do i remove the files?  Its telling me permission denied.  Sorry, i know this is a beginner question.

Yep, get rid of everything. The license base isn't your actual license file, so that will be safe to remove .

do i remove all files including MicroFour License Base from the GAC?

When this happens there is generally an issue with the permissions on the machine or a disk space issue.  The first thing that an update does is attempt to remove the previous install (it is done for you automatically through a pre-req).  Next, the MSI caches itself on the local machine (not my favorite feature of MSI, but necessary nonetheless).  Finally, it just copies the files out.  Then you will see a couple of windows come up during the "Applicaiton Configuration" portion of the install that loads the new assemblies into the GAC, updates structures, etc.

So the first thing that you will want to look at is your GAC.  Do you have SF assemblies in there?  If so, you may want to manually remove them, and the load the install again to see if they get updated. 

This is one of those "how long is a string" questions since the OS and Windows environment come into play.  But your OS and VS versions will work fine, so we just need to poke around a little and see why the files did not get updated.
