multiple WAMP versions (32bit and 64bit)


I'm wondering if it's possible to install a 32bit and 64bit WAMP for Windows 7 (64bit). I don't necessarily need both running at the same time but I'd like to switch between the two bit versions if I have to.

If so, how do I do this? Just install in a different directory?

Thank you,

installing in different directories should work though you may or may not end up with separate php.ini files.

running both at the same time should be feasible providing that your apaches and mysqls do not listen on the same port. you may even use the apache proxy to redirect for example the /32 directory on the 64bits version to the 32bit install and possibly publish the same files on both install

if that fails, virtualisation may be a good way to go as well. i'd recommend virtualbox for it's ease of use and good performance

Hi skullnobrains,

I just tried to install the 32bit in a different directory. What happened is that my 64bit no longer works and I went the the services control panel and I don't see wampapache. I do see wampmysql though. Don't know what happened.

I guess I can try virtualbox. Is it free?


Does anyone else have experience in setting up multiple WAMPs?

the service names are possibly hard coded so you may need to install them as regular programs and not windows services. this is probably true if your new wampmysql service replaced the old one.

the apache service should definitely be there if apache works. maybe wampapache is not the name ?

"no longer works" is by no way enough information for anyone to help

"no longer works" means when i tried to start the WAMP services it didn't start. What I did was uninstall the 64bit version and then reinstalled it.

I didn't see any options to install them as regular programs though. The only option for the installation of the 32bit and 64bit was to install it to a different directory which I did  but the services didn't start. I think the only option is for me to just manually install apache, php and mysql manually.

Are there any known problems for installing 32bit AMP on Windows 7 64bit?

Thank you

I managed to instal apache/php manually. Didn't set up mysql yet though. 32bit versions on Win 7 64.

My debugger for nusphere doesn't work right now. That's another problem though.

Fyi, as thread safe and non thread safe:

A Thread Safe version should be used if you install PHP as an Apache module.

The Non Thread Safe version should be used if you install PHP as a CGI binary.

manually, installing 32bit php/apache on win7 64bit seems to work in conjunction with 64bit wamp.
