Unable to select 32-bit R version in RStudio v1.2.1047-1 Preview

Apparently this was due to a key RStudio development tool no longer supporting 32-bit:

Switch Windows desktop to be 64-bit only

rstudio:master ← rstudio:feature/win64_only

# Summary Switch RStudio for Windows IDE to be 64-bit only. Primary motivati…on is upcoming move to Qt 5.11; Qt is not providing 32-bit build of QtWebEngine in 5.11, so we're taking this opportunity to go 64-bit only on Windows. Doing this first against 5.10.1 to begin testing the waters. This also requires https://github.com/rstudio/rstudio-pro/pull/491 be taken in Pro repo, otherwise Pro will fail to build once this work is merged in. Also removing the 32-bit terminal shell options (Command Prompt and PowerShell); simplifying to 64-bit shells only. # User Impact * user must have 64-bit PC and Windows to run RStudio desktop * user cannot use 32-bit R (won't be shown, and if previously selected will be switched to 64-bit) * 32-bit command prompt and PowerShell no longer available as terminal shell options; if previously selected will be silently switched to the 64-bit equivalent # Technical Details * developer must use a 64-bit kit when building in Qt Creator, can no longer build 32-bit * make-package will produce a 64-bit only Windows installation * in addition to rsession.exe, the following are now 64-bit, previously were only 32-bit: * `rstudio.exe` * `rsinverse.exe` * `urlopener.exe` * `diagnostics.exe` * `consoleio.exe` * `rpostback.exe` * now using 64-bit `QtWebEngine` (due to 64-bit `rstudio.exe`) * removed some runtime logic that was testing if running on 32-bit or 64-bit; Windows code can now just assume 64-bits like we do on all the other platforms * updated the dev machine bootstrapper script to just install 64-bit Qt, save some download time; you can always add 32-bit by running the Qt maintenance tool via Add/Remove programs * updated the script for building boost to just build 64-bit, but I didn't update the package on S3; that can happen later when we bump up to Qt 5.11 and MSVC 2017 * explicitly set our targeted platform at compile-time to be Windows 7 SP1 instead of Vista * fixed a handful of the bazillion warnings we get when building everything 64-bit (size_t vs DWORD, that sort of thing) * updated the copyright year in the setup.exe itself (super-exciting detail, I know!)

@woodward This is unfortunate news. I think this means the likelihood of adding support for 32 bit is slim to none. Thank you for finding and sharing this so I can earnestly look into other IDE's for when I develop scripting that has to query via database.

This is a problem. I just updated to the new RStudio and am now unable to import my PhD dataset from Access to R using RODBC. I have never been able to find a way to do this using 64 bit R. If anyone has a fix at some point I'd be very grateful. Otherwise I'll be stuck on an old version of RStudio for the duration of my project.

Created an account just to say that I am in the same boat here. I downloaded RStudio 1.2 this morning after hearing about all the new updates on LinkedIn, and am disappointed to find out that this release has actually removed such an important piece of functionality.

I use 32-bit R to RODBC into our 32-bit Oracle database. Given that our database architecture will not be changing anytime soon I will have to skip these new releases.

Also created an account for the same reason. Very heartbroken to see that 1.2 does not support 32-bit R. My company will not be changing to 64-bit database anytime soon.

I am hopeful that RStudio will fix this.

Another vote from me. I'm stuck with a 32 bit RODBC connection.

I've reopened this issue to serve as the place to gather feedback and votes on this:

### System details RStudio Edition : Desktop RStudio Version : 1.2.…792 (Preview) / 1.2.822 (Daily) OS Version : Windows 7 x64 R Version : 3.5.1 ### Steps to reproduce the problem 1. Tools > Global Options 2, Click "Change" button in "R version" 3. 32 bit versions of R are not shown (but are installed) 4. Selecting "Choose a specific version of R" > Browse (to R_HOME/bin/i386) and selecting OK does NOT add this to the list of options ### Describe the problem in detail ![image](https://user-images.githubusercontent.com/2107580/42670524-c2574550-869e-11e8-8723-208f24d40c7a.png) ### Describe the behavior you expected Be able to switch to 32 bit R. I can do this with the latest stable release of RStudio (v1.1)

This is a problem for me. My company is still runing MS Access 32bit and I need to access the database via odbc.

GaryR · May 8, 2019, 10:04pm

I apologize for the problems and concerns this has caused.

I have restored 32-bit R support to RStudio 1.2 for Windows. It will be in an upcoming patch release of RStudio 1.2 after it undergoes testing and validation. I will also eventually add this support back to RStudio 1.3.

Please note this will still require 64-bit Windows; this restores the 32-bit R functionality, but the rest of RStudio 1.2 remains 64-bit.

For those who like such things, here's the PR on github: https://github.com/rstudio/rstudio/pull/4775

Wonderful news!

Thank you, and your colleagues, for taking the on board the feedback. I'm so relieved to hear RStudio 1.2 will restore 32-bit R support.
