System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt

Hi,

we are using SIMATIC PCS 7 V8.0 SP1

i have created a wrapper API which will use Interop.IPCS7_SBAPI_XLib.dll to create the batches.

While accessing the API methods, we are getting "System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt"

Not sure why we are getting this error. 

Please help us to resolve this error.

OS - Windows Server 2008 R2 Standard SP1 64 bit

RAM 2GB

Thanks,

Sudhakar

Hi ksudhakar,

I'm not sure if the if the topic which is discussed in another forum is the same. But maybe you can find some hints.

Besides I think your working memory is not enough. Have a look in PCS 7 readme V8.0 SP1 (online).
