Make sure your proxy account has permissions to access the following:

1. The SSIS+ installation folder

2. One of the following registry keys, depending on whether you're using the 32 bit or the 64 bit version:

      32bit - HKEY_LOCAL_MACHINE\SOFTWARE\CozyRoc\SSIS
      64bit - HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\CozyRoc\SSIS
