In this system:

-Clean install of Windows XP (2002 release) with the latest updates.
-VFP7 + SP1
-Admin access to all

I was programming a Single-threaded DLL with no problems, till now that I got
a 0x80004005 trying to run again the DLL.

Tryed to unregister or reregister manually, and I got:

DllRegisterServer error in myDLL.dll. Return code 0x80004005

I have the dll, tbl & vbr files in the same dir, also registering manually in other PC works withouth problems. I searched here if any solution but no one worked.

Now I tried to see the error that DllRegisterServer gives programatically and I get:

-2147467259

With this code

****************************************************
a=RegisterServer("D:\espera3\espera3.dll")
SUSPEND

FUNCTION RegisterServer

  LPARAMETER tcFileName

  LOCAL lnresult
  DECLARE INTEGER DllRegisterServer IN (tcFileName)
  lnresult = DllRegisterServer()
  RETURN lnresult
ENDFUNC
***************************************************************

Perhaps my registry is brokened, don't know why neither wich action leaded to this.

So, question, any more to look or review?

And second, any GOOD registry cleaner/verifier for Windows XP?
