FB1.5.6.5026/w32 Win7 x64/sp1

When I began my transition from Win2k to Win7 x64, I couldn't get any of my apps which ran an fb db to run: it was always "unavailable database" or from a Delphi message box, "check that the database is present." Drove me mad. Then I started changing Win7 user permissions, and finally everything worked again.

Recently I've been having windows problems with dbl-clk not opening pdf and rtf files. So I ran Windows Folder and File fix applet and it didn't find anything. Shortly after I shut down.

This AM all of my fb apps returned "unavailable database" or the equivalent from a delphi app. I mainly use IBO_SQL to do my testing: that's what gives the "unavailable database -904 335544375 error.

I uninstalled and reinstalled twice. Same thing.

So I started looking at my db permissions and they had been reduced. So I gave them full permissions, but I still can't get anything to open.

Running this, however, appears to work:

isql 'C:\Program Files (x86)\Firebird_1_5\examples\employee.fdb -user SYSDBA -password masterkey
CON>

That is, if I can presume that the 'CON>' return means that fb connected to the db.

I'm logged in as an administrative user.

employee.fdb lists full control for SYSTEM and Administrators(MyComputer\Administrators)
Only 'Read & Execute and Read' for (Users\MyComputer\Users)

Any suggestions?
