SMSINST: Iterative Use Of Get Temporary Filename Can Cause an Access Violation (252831)

The information in this article applies to:

Microsoft Systems Management Server Installer 2.0

This article was previously published under Q252831

SYMPTOMS

When you are using Systems Management Server (SMS) Installer Script Editor to assign a temporary file name (Get Temporary Filename into variablename), the generated SMS Installer program can cause an "Access violation" error message similar to:

The instruction at xxx referenced memory at yyy. The memory could not be "read".

CAUSE

This behavior can occur if the Get Temporary Filename script action is used within a loop. For example, the following sample script generates the error message:

Set Variable COUNT to 1
While COUNT Not Equal 200 do
   Get Temporary Filename into MYFILE
   Set variable COUNT to %COUNT% (Increment)
End Block

For small loop iterations (less than 130), the problem does not occur.

WORKAROUND

Do not use the Get Temporary Filename script action in a loop that is likely to iterate beyond 130 times.

STATUS

Microsoft has confirmed this to be a problem in Systems Management Server Installer version 2.0.91.
