Hello,

This error could be caused by many factors. but the most common one is either Com missing/not registered and 32b app pool error on 64bit os.

This is what I would do:

1) Make sure that the com component is present and registered on the server. Use REGSVR32 ComponentName.dll.

2) It is likely that your com com component is compiled in 32bit. If the server is a 64b os (like w2008R2 for example), you need to make sure that the application pool is a 32bit one and not the default 64b. To do this open IIS, create a new app pool, select properties, in advanced settings set "Enable 32b application" to true. Change your website app pool to use this new one.

That should sort out your issues.

Good luck debugging. :)

Valery.
