Excellent - saved me lots of time and blood.


Tried it and it worked! I started a registry search from root location for \Hewlett-Packard\\ and found the same registry location posted by jeon on my HP machine.



Thank you much for the tip! It saved me a bunch of time. I found it only under the following location:

After removing the key, the install worked perfectly :)!

Had the same problem on a new HP machine with the install of MySQL. Used the search, cleared the location; worked like a charm.



I followed the steps to locate [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall] but i can't even find the 'installlocation' directory.There is no such thing as a Hewlett-Packard directory...am using windows 7 64Bit. Is there another way to do this?


Thanks a lot for this information, it does solve my problem.

I have been trying to install MySQL on and off since the beginning of the year and have given up every time, and for some reason decided to try again today. Searched for \Hewlett-Packard\\ and FOUND IT!

By the way, deleting something from the registry felt like doing brain surgery on my dog: Felt like I had no idea what I was doing, but it'd better work, or I'd have some explaining to do to my wife.

Thank you to Steve and everybody else contributing here. I can FINALLY start experimenting with MySQL.



Thanks man! For me it works just fine: i've created hpinstallfix.reg with the info provided, double click and now i can install MySql Server 5.5


Wow, thanks for the fix


Thanks so much! It solves my problem.


This information was extremely helpful, I have to agree with Wayne Fuller, you do not need to delete the value, only to clear the data in the string.



Assisted me with an installation of Milestone xProtect, Thanks!!!


This resolved my issue-was not able to install mimecast ADD-in for Outlook. Thank you!
