After following through to Install, everything appeared to proceed until the error displayed in JPG 01 popped up.
Trying Retry or Ignore bought me back to the same pop-up. Choosing Cancel caused the install to roll back.
See GPG01: VMware Autherization service (VMAuthdService) could not be installed. Verify that you have privileges...
After the above install failed, returning to run the un-patched V15.5.1 bought up the errors seen in JPG 02 and 03.
Searching the Knowledgebase failed to find a fix.
See JPG02: The code execution cannot proceed because pcre.dll was not found. Reinstall program to fix problem.
and
JPG03: The ordinal 407 could not be located in <Program files> libcurl.dll
Anybody have any ideas? Thanks, Greg.
