I just tried to update my Windows x64 VServers and the installation could not complete because it could not find the file:
I have never seen this .dll file with a _1 in the name before. I renamed the existing vcruntime140.dll file to vcruntime140_1.dll and then received numerous entry point errors.
I tried numerous downloads of 9.8 and this error occurred on all my Windows x64 machines. I installed v9.7.4 and all is well again.
P.S. the v9.8 Mac version installs and works just fine.
