Hello I am a mac user and for some time I have been waiting for an update that allows instalation and use of 64 bit drives.

I need this because I use MetaTrader 5 and now with recent updates a lot of the features that were previously available on 32 bit are no longer present because the developers of MetaTrader now expect most/ all their users to be on 64 bit. My mac is already configured as a 64 bit so it is frustrating to not be able to use 64 bit drives on PlayOnMac?

Can you guys help.

From what I understand, the OS X ABI is incompatible with a 64bit version of Wine.

PS. On the other hand, the 1.7.36 changelog mentions something about 64bit on OS X; So I don't know...

PPS Came cross this thread in wine-dev mailing list

It seems to me (according the message) that the app has switched from 32bits (x86) to 64bits (amd64) but the script is set for 32bits.
What is your OS and its version ? (and also: 32bits or 64bits ?).

I’m having the same problem. I’d really appreciate any help of someone who could understand what is happening. Here is a description of what I’m doing:

I use the MAC OS High Sierra

Processor (Core i5), which I believe is a 64-bit processor

I have successfully installed the Play On Mac, and also separately installed the latest version of XQuartz (before doing this, the Play On Mac did not run on my MAC).

Then I select: Install a program >> install a non-listed program >> Manual installation

Two options:

1. Install a program in a new virtual drive

2. Edit or update an existing application (I select this option)

>>Show virtual drives (I select the drive I’ve created, and I don’t know how I did that, just remember the software asked me to give a name to a new driver)

>>What would you like to do before installation?

3 options:

1. use another version of wine (2 options)

  • System
  • The version of wine I have configured. I configured the one is the most recent in the list of Play on mac (4.19 staging).

2. configure wine (If I select configure wine, a window pops up, where I can select the many windows version up to windows 10. I select windows 7, and 10. Both doesn’t work)

3. install some libraries (I don’t select this option)

>> Select the version of installation

I have tried with both versions, none has worked and the same error will occur.

32 bits windows installation

64 bits windows installation

>> Please select the install file to run (I select the “mt5setup.exe”)

And voilà:

Error in POL_Wine

Starting 64-bit process /Users/andersonmelo/Downloads/mt5setup.exe is not supported in 32-bit virtual drives

It doesn’t matter the combination of options I use, the same error will come up at the end.

I have a feeling that some way the virtual drive I created is incompatible with 64-bit version of the software I’m trying to run.

Any help?


Thank you!

Same problem here. Can't instal MT5 , same warning appears about being 64 bits. I erased the wine versions not 64 bits, left only amd64 using 4 and 5 , and still not working . Have anypone solved the problem ? Thanks !

This is how I solved the problem on my macos catalina. After manually downloading the 64 bit wine, Instead of going to metatrader 5 site to download the mt5setup.exe, I searched for metatrader 5 on PlayOnMac and installed it from there.
