Windows: 'update stable' downloads wrong architecture

[matkuki]

Hi,

My specs: Windows 10 x64, choosenim installed manually.

I had installed 1.6.8 previously a couple of months ago with choosenim update stable and it worked without problems.
Tried the same with 1.6.10 a couple of days ago, but it downloaded the x86 version. Here is the forum post I posted the problem on: https://forum.nim-lang.org/t/9643. I removed 1.6.10 and reinstalled it at least twice with:

choosenim 1.6.8
choosenim remove 1.6.10
choosenim update stable

... but each time it downloaded the wrong architecture.
But after a day, maybe because of a reboot or something else (I honestly don't know what else could it be), it worked?

Any ideas what went wrong here?

Here is the same problem with Nim 2 RC1:

It happened to me the other day too on Windows, I think when trying to upgrade to 1.6.12. Deleted everything choosenim and nimble related and reinstalled, and got x64.

Hey @daniel-j

It happened to me the other day too on Windows, I think when trying to upgrade to 1.6.12. Deleted everything choosenim and nimble related and reinstalled, and got x64.

I tried that, no changes.

NEW OBSERVATION:

choosenim update devel while located in the C:\ or C:\Windows\ or C:\Windows\System32 or ... directory installs wrong version:

C:\WINDOWS\system32>choosenim update devel
   Updating devel

choosenim update devel in any other directory like C:\Users\ or C:\Nim or C:\whatever installs correct version:

C:\Users\matic> choosenim update devel

Where is the heuristic to detect the architecture on Windows in the code located?
