    Java Mission Control - Windows7(32bit) - hsperfdata_<name> : How to stop JMC installation locking this folder?

    Westy_007+half

      Hello, I hope you're sitting comfortably; I will begin.

       

      1. Have tried all week, on and off, to install Android Studio; the **** thing fails to launch: "does not point to a valid JVM installation."

      2. So un-installed Android Studio and Java, followed by a quick spring clean around the registry area...

      3. Java 32bit Developer Kit version 8 update 162 was duly installed, but the re-installed Android Studio still failed to launch. "Mission Control we have a problem!" [that's me speaking :-(]

      4. The hsperfdata_<user> folder had indeed been locked, as the launch error message suggested. [see attached]  So I unlocked it, but didn't go inside - honest...

      5. Another un-install, re-install trip to the launch pad failed to ignite Mission Control. The hsperfdata_<user> folder had been re-locked! The folder's security properties had reverted to 'special'!

      6. Whilst I was tinkering under the bonnet - that's hood to our American friends - changing the inherited permissions back; some bright spark (genius) at JMC Frequently Asked Questions said to also look into the jmc.ini file. I don't have a jmc.ini file! Well, not where he said it should be - JAVA_HOME/lib/mission control/jmc.ini

      7. Another few trips to the launch pad followed, using various combinations of permissions with and without virus protection/firewall. Still no joy.

       

      This concludes my sorry tale, to date. But forever hopeful that some kind sole will help to get Mission Control off the ground before I start running.

       

      Away,

      John
