The error code is 2739

I had been trying to install later beta Skype clients, but to no end. I kept seeing this error message:

Skype: The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2739.

But when that error dialog popped up again with a final build (2.6 was released yesterday), I went Googling for it. Lo and behold, the answer was there – on Adobe’s site, not Skype’s (that I could tell). Their solution worked, although they were slightly incorrect by stating that the workaround would involve editing the Windows registry.

No, all you have to do is re-register the jscript.dll file. Don’t you love DLLs? The more things change, the more they stay the same. Here’s what I did:

  1. Hit Windows+R to bring up the Run dialog
  2. Keyed in “regsvr32 jscript.dll” (without quotes) and hit Enter
  3. Clicked OK on the resulting success dialog
  4. Installed Skype without a hitch

    You may need to authenticate if you’re one of the devoted UAC faithful – and you’ll definitely need administrator privileges. To my knowledge, Mac users only have a single Skype binary to deal with?
