Just wondering if anyone has successfully installed 11gR2 64-bit on windows 7 64-bit (ent edition of win7)? If not, has anyone seen/solved symptoms like these: With various permutations of install options, response-file based silent or UI interactive installs, the setup consistently crashes out (literally, the binary simply terminates). This is usually happening at the end of the prerequisite check phase (so all the values for sid, service, storage, passwords etc. are done), just before the summary screen should appear and the install actually starts. The oraInstall<datestamp>.out and .err files are always zero bytes in size, and the tail of the installActions<datestamp>.log file usually looks something like this: INFO: Verification Result for Node:<my hostname here> INFO: Expected Value:64-bit INFO: Actual Value:64-bit INFO: ----------------------------------------------- INFO: ********************************************* INFO: Environment variable: "PATH": This test checks whether the length of the environment variable "PATH" does not exceed the recommended length. INFO: Severity:CRITICAL INFO: OverallStatus:SUCCESSFUL INFO: ----------------------------------------------- INFO: Verification Result for Node:<my hostname here> INFO: Expected Value:1023 INFO: Actual Value:890 INFO: ----------------------------------------------- INFO: All forked task are completed at state performChecks INFO: Completed background operations INFO: Moved to state <performChecks> INFO: Waiting for completion of background operations INFO: Completed background operations INFO: Validating view at state <performChecks> INFO: Completed validating view at state <performChecks> INFO: Validating state <performChecks> INFO: Using default Validator configured in the Action class oracle.install.ivw.db.action.PrereqAction INFO: Completed validating state <performChecks> INFO: Verifying route success INFO: Get view named [SummaryUI] And that's all the diagnostic info I can find. Nothing in the windows event logs, UAC has been disabled (and I've tried running setup attempts explicitly as "Run as Administrator" with no luck). I checked metalink/mos, but there's no detail I can find there. Before I bother opening an SR, I thought I'd ask here ... this is just one of my test notebooks, so it's not critical ... just really annoying. Ciao Fuzzy :-) -- //www.freelists.org/webpage/oracle-l
