The installation of the prerequirement “Microsoft Visual C++ 2017 Redistributable Package (x86)” seems to be corrupt in the following scenario: 1: Install a complete new Windows 10 x64 version 1809. 2: Run our installation (build from InstallShield 2016) from a mounted iso, using Windows 10 build in mounting feature. Several prerequirements is prompted (See attached image img1.png) to be installed. When the “Microsoft Visual C++ 2017 Redistributable Package (x86)” is installing it requests for reboot. 3: After reboot, the user must manually mount the iso again. When restarting the installation (setup.exe) the prerequirement is prompted to be installed again, but this time, this prerequirement reports an installation error. 4: When starting our application, we got error messages (See attached image img2.png) and another message telling “The code execution cannot proceed because VCRUNTIME140.dll was not found.” We have not found any way to solve this or fixed the corrupt installation. Tried to reinstall every prerequirement but noting we do help except for reinstalling Windows.
