Hi,

I have a program written in VB6 which works perfectly well on all my development machines which run XP / O2k3 / VB6. However I am trying to get it to run on a system running MS Small Business Server 2008 (64-bit) and am having trouble registering mscomm32.ocx

I have copied the files mscomm32.ocx and mswinsck.ocx from an XP machine. When I run the command "regsvr32.exe mscomm32.ocx" I get the following error message

The module "mscomm32.ocx" may not compatible with the version of Windows that you're running. Check if the module is compatible with an x86 (32-bit) or x64 (64-bit) version of regsvr32.exe.

I get an identical message when I try to register mswinsck.ocx

Can anyone advise me how I can register these or obtain versions of these files which will work on this system.

Thank you
Darren

You're running the 64 bit version of regsvr32 (ironic, huh?).

You need to run the 32 bit version, which is here:

%SystemRoot%\Syswow64 folder.

For example, type the following commands to register the DLL:
cd \windows\syswow64
regsvr32 c:\filename.dll

You, Sir, are a genius. Thank you!

The ocx's registered perfectly but I now have an unrelated issue with wmp.dll

I do have a control which uses wmp but I'm going to disable it now and see if my program runs and uses successfully mscomm successfully.

Back shortly...
