MSVCR80.DLL version conflict

I have a C++ ActiveX control that is used by JavaScript code in*
Internet Explorer. Recently, a customer installed Acrobat Reader 8.1*
and reported that the ActiveX control wasn't working. In the event*
viewer, there's a error from SideBySide: "Generate Activation Context*
failed for ... . Reference error message: A component version required*
by the application conflicts with another component version already*
active."

Investigation showed that before Acrobat was installed the control was*
using msvcr80.dll requesting 50727.104. If I closed the control and*
installed Acrobat, msvcr80.dll version 50727.163 was immediately*
loaded by Internet Explorer. When we tried to load the control, it*
wouldn't start and the error message was put in the Event Log.

I noticed that the redirect in in the 8.0.50727.163 policy redirected*
8.0.50727.42 to 8.0.50727.163 but didn't redirect 8.0.50727.104. If I*
added a redirect for 8.0.50727.104, the control started fine.

It also started fine if I installed SP1 redistributable.

Why is 8.0.50727.104 not redirected? I thought the whole purpose of
the*Side By Side software was to allow multiple versions of the dll to
run*at the same time. Is that not correct? How does it apply in this
case?

Thanks

Mike

Hi Mike,
I just got the confirmation from the Dev team. It is confirmed that this
issue was an older product issue and had been got fixed in the latest
service pack SP1. I think that that is why it started fine after you
installed SP1 redistributable.

They recommend that you redistribute VS2005 SP1 CRTs with your ActiveX
control so that this issue will not happen again.

Please feel free to let me know if you have any questions or concerns. Have
a nice day!

Best regards,
