Hi Peter and thanks for your report. Can you please test with latest release, 5.1.2.? I
tested and found no problems...

Waiting on your results.

That was what I did acutally.  Installed 5.1.2 on top of 5.1.1.
This could be an old issue from installing 5.1.1 on top of 5.1.0 however. 

I will 
1) uninstall and if required clean the registry for all entries
2) install 5.1.1
3) install 5.1.2

and report back!

Peter, thank you. Waiting on your results.

reproduced.

One change however.  I installed 5.1.2 on top of 5.1.0.

After first report I uninstalled the driver.  One entry in uninstall menu disappeared (as
expected).  Trying to uninstall the other one returned 'action only valid for installed
programs'. After seacrhing registry for "odbc 5.1" and delteing everything related (there
was quite a lot actually) the orphaned entry disappeared from uninstall menu.  Now
installed MyODBC 5.1.0.  One entry in uninstall menu appeared.  Next installed 5.1.2  Now
two entries are there!

Actually I found that I have a Microsoft program that did the same! 

One 'sideeffect' is that after uninstalling the driver still appeared in 'computer
management .. odbc' .. but not functional of course!

Was 5.1.0 using the wix-2 installer? Maybe this was a problem with wix-2 or having  the
wix-3 installer correctly update the installation.

Hi Peter. Can you please do as Jess asked and test only install/uninstall of 5.1.2? There
were changes in installer which might have fixed this. Did you do install/uninstall from
privileged account? I tried this during my normal work and found no problems, but I only
have Vista x64 business.

I can try .. but may take up to a couple of days.

Peter, waiting on your result.

I uninstalled and removed everthing related to MyODBC 5.1 and 3.51, rebooted, installed
both, uninstalled both, rebooted.

Now from a user's point of view it is (almost) OK.

However there still are obsolete registry entries after uninstall.  I attach those as a
zipped archive.

Also I am not able to verify that every file is properly deleted as I do not know what
files are copied and where.  I think you should verify!

I still think it is a BUG that *upgrading* does not clean up garbage from previous
versions!

*obsolete* .. of course!

alternatively ...

If 5.1.2 cannot clean up after 5.1.0 then it should refuse to install and prompt user that
5.1.0 must be uninstalled manually first.

Peter, I just checked my Vista Ultimate x64 and could not repeat your problem... I don't
say it does not exist but that's the reason we have alpha / beta etc releases. As far as I
know, installer version changed from 2 to 3 between alpha and beta so problems like this
might be expected. However I'll set this problem to "Verified" so our doc-master, MC, can
add a line or two of warning.

Thanks for your interest in MySQL.

ok ...

I think that my screenshots are undisputable!?

But if it does not happen all time, I do not know what triggers this.

It is not a big issue.  But basically I think that MySQL AB should focus more on/test with
Vista.  Install .. use .. uninstall.  I have another report with installer issues on Vista
open. Also a few days ago I installed server 5.1.23 and latest connector .NET.  Also those
had some small issues with the installer on this system.  What I remember:

* installer for 5.1 server was not able to stop or start running service
* one of those installers printed outside the dialogue box.

Maybe however I should have told that my OS is Vista 32 bit SP1 (RC).
Hardware Athlon Dual Core 64 bit (a HP series 9xxx laptop), Graphics is a typical Nvidia
system for laptops.

I find small issues with practically every recent installer for Windows.  And that was not
so a few years ago!

Hi Peter.

> I think that my screenshots are undisputable!?

Yes, I can't tell you you're imagining this :) although I can't repeat.

> But if it does not happen all time, I do not know what triggers this.

Neither do we. I asked doc-team to add a warning.

Well, we are committed to making things as best as possible, but a minor errors are bound
to happen. We don't like that, be it even half baked soon-to-be-dead "shiny" new OS from
you know who.

Ok, I tested on Athlon x64 + nVIDIA too but with Vista Ultimate x64.

> I find small issues with practically every recent installer for Windows.  And that was

We have changed several installers lately in search for one that suits us best and we're
not yet familiar with all the features / tricks.

My colleagues have failed to repeat the problem on Vista business 32bit...
"But bug is not repeatable for me too: I get warning about another version of the product
installed and installer quits."

I will let Georg close this as he sees fit.
