As per our call, please change the registry key for each instance of LinkFixer that have a C: Drive partition of less than 500GB.


 You could move the LinkFixer "working storage" folder to another location. 


The AppData folder is stored in the registry:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\LinkTek\LinkFixer Advanced] 
  (actual registry key location)
"InstallFolder"="C:\\Program Files (x86)\\LinkTek\\LinkFixer Advanced"
"Desktop"="C:\\Users\\Public\\Desktop\\LinkFixer Advanced"
"LogFolder"="C:\\Users\\Public\\Desktop\\LinkFixer Advanced\\Logs"

"AppData"="C:\\ProgramData\\LinkTek\\LinkFixer Advanced"    (this is the default for the temp folder)



 Create another folder on another drive and manually update the registry setting.

 Make sure LinkFixer is not running when you make this change.
