A portable app does not need a traditional installation. It runs directly from a USB drive or a folder on your hard drive. The program should launch immediately
| Problem | Likely Solution |
|---------|------------------|
| “Cannot find VBRUN300.DLL” | Download and place VBRUN300.DLL in the Presto folder or C:\Windows\SysWOW64 (for 64-bit systems). |
| Screen flickers / weird colors | Enable Reduced color mode (16-bit) in compatibility settings. |
| Mouse doesn’t work properly | Presto 8.8 is keyboard-first. Use arrow keys, Enter, and F-keys. |
| Error: “Record locked” | Ensure no other user has the same file open. Delete any .LCK files in the DATA folder after closing Presto. |
| Can’t save changes | Run PRESTW.EXE as Administrator, or move Presto to a user-writable folder (e.g., C:\Users\YourName\Presto88). |

Because it’s portable, no installation or registry changes are required.
The program should launch immediately. You’ll see the classic Presto! splash screen, then the main Database Window.
🟢 Success indicator: If you see a blank grid or a sample database (like "Library Demo"), the portable version is working correctly.
