Class does not support automation.

[vbguy805]

Hi,
I have installed Pervasive V8 on server. When I run my vb app which use pervarive driver I get an error "Runtime Error `430': Class does not support Automation or does not support expected interface"
There is microsoft kb on this it says use RegSvr32.exe , unregister old dll & re-register new dll.

http://support.microsoft.com/kb/193172

Not sure which dll to unregister and what is new dll. Any idea?
Same setup on my desktop works fine.

Which "pervarive driver" are you using?
If it's the Pervasive ActiveX control, then you'll need to distribute the OCX files (ACBTR7.OCX and ACCTRL.OCX -- I think) and you'll need to register them with REGSVR32.

Thank you for ur response..Dont know lot about this..But I am using datadirect 50 drivers..How do I find out what files i need to register? Just look for those files on server? are those pervasive 8 drivers?When i install PV8 or DD50,dont these files get registred?

PV8 won't register DD50 drivers. DD50 won't register PV8 drivers.
I don't know anything about the DD50 drivers. I've never used them. As far as PV8 goes, the only drivers that might give a 430 would be the ActiveX control. If your app doesn't use them, then that's not an issue.
You'll need to debug your app a little bit to find out what line of code is actually generating the 430 error.
