Third-party programs that require lots of memory do not run in Windows XP Service Pack 2

SYMPTOMS

Some third-party programs do not run after you install Microsoft Windows XP Service Pack 2 (SP2). When this symptom occurs, you may receive an error message that is similar to one of the following:

• "Not Enough Memory"
• "Out of memory"
• "Not enough storage"

Cause

This problem occurs if the third-party program has to reserve lots of contiguous memory. For example, the problem occurs if the third-party program has to reserve several hundred megabytes of contiguous memory. The new Xpsp2res.dll file that is added in Windows XP SP2 loads into memory at location 0x20000000. This causes the virtual memory that is available to the third-party program to be fragmented.

Resolution

Hotfix information

Important This hotfix includes a new Xpsp2res.dll file that dynamically finds a memory location to reduce virtual memory fragmentation. Before you apply this hotfix, we recommend that you ask the vendor of your programs to verify that this solution is acceptable.
