Installation/uninstallation problem

rvr · Post by **rvr** » Mon 12 Dec 2005 15:40

Hi,

We installed the demo version of MysqlDirect on 2 computers with Windows XP SP2 and they worked fine.

Windows Event Viewer generated this log:

Product: Core Lab MySQLDirect .NET Data Provider Trial -- Installation operation completed successfully.

Now that we have the registered version, I am trying to uninstall the demo version but I get this error:

Product: Core Lab MySQLDirect .NET Data Provider Trial -- Error 1722.There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor. Action UninstallAddin, location: C:\WINDOWS\Installer\MSI10.tmp, command: "MySQLDirect .NET" "C:\Programas\CoreLab\MySQLDirect.NET\" "VS70, VS71" MySQLDirect "CoreLab Database Developer Tools"

Questions:

1. What caused this error?

2. Do I need to uninstall the demo version (3.0) before installing the registered version?

3. The error occurred about two-thirds of the uninstallation and very likely that I uninstalled some necessary files. If I don't fully uninstall the demo version, will this not cause any future problems? I wouldn't want to format the hdd's on the 2 machines just to get rid of the demo files.

4. Is there a workaround in Windows registry to fully disable the demo version?

Any suggestions would be most welcome.

To remove MySQLDirect .NET manually you should:
Stop Windows Installer service;
Delete key in the registry
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products
that corresponds to MySQLDirect .NET;
Delete key in the registry
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Assemblies
that corresponds to CoreLab.MySql.dll;
Remove all CoreLab.* assemblies from GAC;
Stop IIS service if you install Web demos virtual directories;
Remove \Program Files\CoreLab\MySQLDirect.NET folder.
After that you can install MySQLDirect .NET again.

Hi Serious,

Following your instructions, I got this error during the installation:

Anyhow, I deleted all entries of "corelab" and "mysqldirect" in windows registry (a couple of dozen of them!). Also deleted all files in drive C: with string " mysqldirect.* ".

I checked Event Viewer and came up with this (believe it or not):

The installer is looking for user data from Microsoft Word....

... and user data from MS Access!!

Both Word and Access are installed in computer-1, but never been used yet so I opened both apps and entered the user initials. That done, I proceeded with MysqlDirect installation.

During install, MysqlDirect asked if I want to Change Install Options, Repair, or Uninstall. I clicked on repair and installation finished smoothly.

Question:

What has MS office apps got to do with the installation? something to do with msi configuration???

I'll be working next on the second machine... see what comes up.

Thanks.

Hi to all,

OK, it's confirmed on 3 machines:

Mysqldirect won't install properly if Word and Access are not installed AND must have user data.

The first machine was XP Portuguese, the other 2 are both English. That rules out regional settings.

Me and my colleagues can continue with our project. If anything funny comes up again, I'll post back.

Regards,
RVR

ps: Dear readers, please post comment if you had similar experience or have any idea why our installation behaved this way.

MySQLDirect .NET doesn't require MS Office or any other third-party product being installed.

As for installation error. It is caused by Hxds.dll missing or unregistered. This library is required to register or unregister help files.
