[ISS Support Case] Updating MS Visual C++ Libraries on AVEVA 2020 R2
Last updated: March 6th, 2025Description
I support WonderWare 2020R2... We use WonderWare to control our production process throughout our packaging facility here with 25+ Wonderware clients running. Recently, we have discovered that it appears a newer version of C++ has been installed on our PCs and it is breaking WonderWare 2020R2. The Intouch HMI viewer will no longer open and reports multiple dll file missing errors related to Visual C/C++. We have discovered a workaround that if we uninstall the newer versions of C++ from the machine and then repair wonderware, it will alleviate the issue. However, this feels like a bandaid and is only limping us along until the next time it installs. My questions are: 1. Is there a way to force WonderWare to ignore newer C++ installs and just use the version thats compatible? 2. Are there any other things we can try that dont involve upgrading our version to troubleshoot this?
