VMware tools install fails with “An error occurred installing the package. Windows Installer returned ‘1601’”



I have been getting An error occurred installing the package. Windows Installer returned ‘1601’ while installing/updating VMware tools on 1 VM (out of like 70..) for some strange reason. Fast forward some time and its all apparent now:

Its one of those annoying things you could really could do without on a Friday evening!!

Anyways, that’s that sorted – time to pack up and leave for the day.

VMware ESXi 5 Error “XXX esx.problem.syslog.nonpersistent.formatOnHost not found XXX”


Here is rather not interestingly looking error message popping up when you don’t have Syslog configured properly on ESXi 5.x. I have seen few variations of this error but only have one screenshot at hand!

    Converting template to a VM fails on “This Host or Cluster is not Valid Selection”


    So here I am, sitting at 10PM converting templates (.vmtx) to VMs (.vmx) – nothing simpler to do right? Wrong!

    And the solution (as usual, very simple) is to manually remove any entries to .iso files referenced in .vmtx file. I had one to volume where the .iso used to sit that was no longer connected as storage to my ESXi host:


    Now you can happily click your favorite ‘Next’ button just to see it completing without problems.

    Life is awesome!
