Just curious to know if the xoops can run on any linux despite which is 32bit or 64bit.

I am going to try this xoops, and do not know if I need a 32bit linux or 64bit linux, for I can not run 64bit on my vmware workstation. which need me to turn off intel trusted execution and turn on the VT-x. I do not want do this for I am not sure if it is safe to my computer if I turn the trusted execution off.

It shouldn't make any difference...

Mamba is correct it does not make any difference.

As long as you have a compatible version of PHP and of a compatible database it should work fine. Doesn't matter if you are running winCE on an old phone with little power, 64 bit Windows Server, 32/64 bit Linux, MacOS, etc... If it runs a compatible version of PHP and has a compatible database you are set. The bit depth of the supporting operating system is handled by the PHP language as is the same for the database so doesn't matter.

In general however if you can run 64bit OS it should be faster. While windows 7 and older may have issues between 32 and 64 bit hardware drivers I have not as of yet heard of issues between 32/64 bit versions of Linux or Win 8. (I believe MacOS and windows server since 2012 are 64bit only)
