Hotfix Not Downloading

If a Peresoft hotfix fails to download or install via the Check for Product Updates function, work through the checklist below.

If a Peresoft hotfix fails to download or install via the Check for Product Updates function, work through the following checklist:

  1. Check internet file size limits. Some network or browser settings cap the size of files that can be downloaded. Check your internet security settings for any file size restrictions.
  2. Add Peresoft as a trusted site. In Internet Explorer or your Windows Internet Options, add peresoft.com and peresoft.co.za to your Trusted Sites list. This is required for the download and for licence activation to function correctly.
  3. Check that program files are not read-only. Navigate to your Sage 300 and Cashbook program directories and ensure the folder and files are not set to read-only. Right-click the folder, select Properties, and uncheck Read-only if set.
  4. Log in as Administrator - not just with admin rights. Run the hotfix installation by right-clicking and selecting "Run as Administrator," or log into Windows using the actual Administrator account. Having administrative rights assigned to your user account is not always sufficient.
  5. Reset the server. If the server has been locked by another user or a process is still in memory, reset the server before attempting the download again.
  6. Check antivirus settings. Some antivirus programs impose their own file size download limits or block executable files from running. Temporarily disable the antivirus or add an exception for the Peresoft directory and retry the download.
