Access Violation in MSVCR90.dll

Access Violation in MSVCR90.dll

The problem may occur with V10 on Windows 10 (version 1803 or later).

The ActiveX Control in V10 is based upon Visual Studio 2008 SP1 ATL templates. Since Windows 10 version 1803 we have seen stability problems connected to Office applications - it seems there was a change regarding ActiveX handling and/or container events. Please note that the official support for the Visual Studio 2008 Runtime by Microsoft ended in April 10, 2018.

Suggested Solution

The stability problems do not occur in TBarCode SDK V11.8+, which is based upon the newer Microsoft Visual C++ 2015 (Update 3) Runtime. We recommend to update the ActiveX Control to V11, which may require also a license update. Updates are free of charge if you own a priority support agreement.

Workaround

If you don't want to update to TBarCode SDK V11 for now (or you need a temporary solution) - you could try to run your application in a compatibility mode for a previous Windows version like shown here. We have seen that this helps in about 90% of the cases.
