The folder created by using jv16 PowerTools 2014 in "C:\Documents and Settings\Administrator\Local Settings\Temp" should be "C:\Documents and Settings\Administrator\Local Settings\Temp\jv16PT_2014" NOT "C:\Documents and Settings\Administrator\Local Settings\Temp\jv16PT_2013."
Log files created in "C:\Program Files\jv16 PowerTools 2014"
Have you tried:
Tools > Program Maintenance > Delete temp files
Tools > Program Maintenance > Remove Registry Compactor backups
Maybe this could help...
