The voting software uses a collection of files and it's essential that all are accessible. This error will state which file cannot be found.
All of the voting elements can be found in Program Files (x86) in the ppvote folder. Check there to see whether the file that the message names is present.
If the file is missing, re-install the ppvote software.
If the file is present, you will need admin rights to run a batch file, so may need assistance from your IT support.
Look for the file name reg_ppvctrl in the ppvote folder. Right click and select Run as administrator.
