DOCUMENT:Q212854 22-MAR-2001 [sms] TITLE :SMSINST: Overwritten Files Are Not Restored During Uninstall PRODUCT :Microsoft Systems Management Server PROD/VER::2.0 OPER/SYS: KEYWORDS:kbinterop kbClient kbConfig kbServer kbsms200 kbsms200bug kbAdvertisement kbPackage kbs ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Systems Management Server Installer version 2.0 ------------------------------------------------------------------------------- SYMPTOMS ======== When you uninstall a program created by Microsoft Systems Management Server (SMS) Installer, the installer does not restore any files that were overwritten by the initial installation. CAUSE ===== This behavior is by design. For example: Consider a user who installs program A with version 1.0 of a DLL, and then installs program B with version 1.1 of the same DLL. The user later installs program C with version 1.5 of the same DLL, and then decides to uninstall program B. If SMS Installer were to restore the version of the DLL that it overwrote while installing program B, it would restore version 1.0, which would likely break program C because program C requires version 1.5 of the DLL. It is recommended that you configure SMS Installer to back up overwritten files. Doing so allows these files to be preserved in a separate directory, from which they can be manually restored if necessary. MORE INFORMATION ================ To learn more about creating backup copies of replaced files, refer to the SMS Installer online Help.
