Hi All,

I am trying to install genmapp on windows XP 64 bit computer. I am
getting the following error.

=============================================================
MDAC 2.7 Sp1 cannot be installed on the machine. MDAC 2.7 Sp1 requires
any one of the following configurations.

----

Microsoft Windows XP

Setup will exit now. Please restart the Setup after installing the
necessary updates to this machine.
=============================================================

I installed all availaible updates. Even installed MDAC 2.7 Sp1 from
microsoft, but Genmapp is still not installing.

Any help would be very much appreciated.

Thanks and Regards

Hello Jai,

GenMAPP was not designed for 64-bit systems and from the little
experience we have with it, the conclusion is that it doesn't work
well. I apologize for the inconvenience. The next version of GenMAPP
will be cross-platform compatible. For now, take a look at the
PathVisio program (http://www.pathvisio.org/Main_Page), this may work
for you.

Regards,

Kristina

Hi Kristina,

I think the problem is because XP 64 bit OS comes with preinstalled
MDAC 2.8 sp2. And thats the reason genmapp is not able to install the
previous version of MDAC (as windows does not supports automatic down-
grade).

Right now I am looking for ways to downgrade MDAC 2.8 to MDAC 2.7. If
I get any sucess, I will write to you.

Isnt there a way to by-pass MDAC installation during Genmapp
installation, and may be it might install up.

Thanks and Regards
Jai

Hi Jai,

There isn't a way to bypass the MDAC installation in the current
GenMAPP installer.

Please let us know if you are able to install GenMAPP after
downgrading the MDAC.

Thanks,

Kristina

Hi Kristina,

I think the problem is due to XP 64 already preinstalled with MDAC
2.8, and therefore Genmapp not able to install MDAC 2.7 Sp1. (Windows
by far does not support easy down-grade)

May I know, when is the expected release of the cross-platform version
of Genmapp.

Thanks and Regards
Jai

Hi Kristina,

I was not able to downgrade MDAC. But a different trick worked out. I
am mentioning this, as this might be a help for others who are using
64 bit OS.

1) Download Windows Virtual PC 2000.

2) Install XP 32 bit on the virtual OS. Very simple to do. Its much
easy and better than dual boot as one can parallel work on both OS.
3) Install Genmapp on the virtual OS.

Thanks and Regards
Jai
