Open File Security Warning When Running Sage 100 ERP

In some cases you may notice that shortly after installing Sage 100 to a workstation that you see a constant warning each time you click to open another menu within Sage.

The warning generally will be “Open File – Security Warning”.

And while you can click to close and ignore the error – it can get tiring having to close so many windows. Here’s one way that I’ve found to fix the issue:

First, be sure you have a backup of all relevant system files. We are not responsible for changes made to your operating system:

1. Click Windows Start. Click Run. Type gpedit.msc and press ENTER.
2. Expand Local Computer Policy, User Configuration, Administrative Templates, Windows Components, and Attachment Manager.
3. Right-click Default risk level for file attachments. Click Properties.
4. Click Enabled.
5. Right-click Inclusion list for low file types. Click Properties.
6. Click Enabled.
7. In the Specify low risk inclusions field, type pvxwin32.exe.
8. Click OK.

This information relates to Sage 100 ERP (formerly Sage ERP MAS 90 and MAS 200) and should work for all versions of Sage 100 – including Standard, Advanced and Premium.
