Any thoughts on why an installshield call to 'RunOICommandPanel' might fail?

We have an installshield script that we use to perform all our updates.

Nothing too fancy. With our latest update, we have tried to update 3 different customers and the 'RunOICommandPanel' statement has failed on each occasion. The odd thing is, we call it a couple of times within our script and each customer is failing at different points.

We have been using the same script for a couple of years without issue. The only time we have had issues in the past is when we've been without admin rights to the machine. Easy to rectify and not the issue on this occasion.

We ran the updates locally without any issues but haven't had a successful customer update in the last two days.

Is anyone aware of any common issues that we may have overlooked?

Each of these commands have failed at different sites:

szCommand=RUN PowerForce_Release_Sub '" + TARGETDIR + "', '" + sPFVerion + "', '" + szRelFile + "', '" + szRDKDir + "', 'CHECK_VERSION'" ;

nRetVal=RunOICommandPanel( hWindow, szCommand );

szCommand=RUN RDKINSTALL '" + szPRE_RDKDir + "','" + szAccount + "'" ;

nRetVal=RunOICommandPanel( hWindow, szCommand );

szResultsFile=TARGETDIR^"ISResults.txt";

if DeleteFile(szResultsFile) < 0 then error processing

Look forward to any suggestions.

Mark
