Description:
Hi

I need to install both the x86 and the x64 version of MySQL for testing purpose. I am using the MySQL installer Community Edition. But once the MySQL Server x64 is installed, the MySQL x86 is greyed as not been instalable...

By the way, rebooting for completing the installation is quite annoying when one have dozen of application opened. The installation process should not need a reboot!

Cheers

How to repeat:
1/ Install MySQL 5.7 x64 using MySQL Installer
2/ Install MySQL 5.7 x86 using MySQL installer

"
1) either tell me that before a 32 bit can be installed the existing 64 bit must be remvoed
2) or allow for parallel installation of 32bit and 64bit of same major ('x.y') versions.
"

1) is the case with Oracle/MySQL (in my experience)
2) is the case with MariaDB (comfirmed on MariaDB mailing list)

There is a need for allowing for parallel installation of 32bit and 64bit of same major ('x.y') versions, since the unit tests are run with both architectures for the same major MySQL version.

Thank you for the bug report. Verified as described.

We need to first check if we can install manually both x86 and x64 versions of the same Server version in a x64 Windows machine, via stand-alone MSIs.
If both Servers can run at the same time we need to check with the Server team if there are no known issues running both architectures of the Server in the same machine.
If no problems can be found we may need to remove the constraint in the MySQL Server, which is now intentional.
