1. Are you running the package on the flash drive connected to the same computer where the package worked when run from the computer's hard drive, or is this another computer altogether?
2. Was the package built on a clean virtual machine, or was it created on the same system that ran the virtualized version successfully from its hard disk?
3. What OS and platform did you use to create the package, e.g. Win7 SP1 x64?
4. On what OS and platform are you testing the package, e.g. Win8.1 x64?
The article in the above link provides 5 solutions to the error "acrobat failed to load it's core dll".
I tried solution #2 , but it did not work.
Solution #4 says "Make sure that Adobe Acrobat or Abobe Reader are installed to the local system drive. Installing on a Mapped Drive is not a supported configuration".
Could this be the problem ?
The Packaged adobe acrobat thinks that the flash drive is a mapped drive and it will not run from a flash drive ???
