You may encounter problems running TopRank with Windows 3.0 or 3.1 on computers with low system resources or low available memory. These are symptom of memory or resource shortages in TopRank:
---Not Enough Memory message
---General protection faults (GPFs) in VBRUN300.DLL or DDEML.DLL
---TopRank freezing or locking up Windows
---All zeros (0) reported in simulation results
---Error code 20032:6
---Error code 20226:360
---"No return or halt found on macro sheet" message
Before running TopRank, check the available memory and resources using the About Program Manager command in the Help menu of the Windows Program Manager. The About Program Manager dialog box lists two important values: Memory and System resources. Later in this document are guidelines for these settings which will help you use TopRank successfully.
