Is R compatible with windows 8.1 64bit edition? - r

I have installed the latest version of R from the official site
However when I open it it takes some time to open. I have tested it in Windows 7 64bit edition and it opens very fast.
Is there any known and common problem for windows 8.1?

Is it possible to run a Qt 5.10 programm on XP?

I have deployed a 5.10 32bit msvc programm.exe and it works ok on windows 8.1. But I have to run it on XP and I can not do it. It says "progamm.exe is not a valid Win32 app". Am I doomed? Do I have to use the last version of Qt that supports XP, like Qt5.6?
Thank you!
The latest version that supports XP is Qt 5.6.3. The Windows XP support is not enabled by default. You have to download the Qt source-code and compile it with ./configure -target xp. This means, if you install Qt 5.6.3 (pre-built) package the Windows XP support is not enabled! You must compile the source-code.
Qt 5.6.3 is in strict phase and reliable if you want to support Windows XP, which is still installed on many computers in China, India, etc.
Qt 5.6.3 is upwards compatible and supports additional to Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10.
Qt 5.7 and upwards do not support Windows XP. If you modify the PE-Header to make it run, it's likely that the application will crash from time to time as Windows APIs are required that are not available on Windows XP.

VS Community 2015 - No Windows Phone Emulator Installed

I get the following error when trying to build (Debug > Windows Phone > Device) the default Cordova TypeScript project :
No Windows Phone 8 emulators installed. Please install Visual Studio 2013 with Windows Phone 8 tools selected to install the emulators
Note: I was using the release candiate of Visual Studio 2015 and just installed the trial version of Visual Studio Community 2015.
Installing Visual Studio 2013 Windows Phone 8 tools can't be the correct solution.
I've downloaded and installed wpsdkv80_enu1.iso from http://www.microsoft.com/en-us/download/details.aspx?id=35471. It is Windows Phone SDK 8.0 and Emulator and it's working fine with Visual Studio 2015 Community
If you want to only test universal apps, you don't need to download WP SDK 8.0.
You can debug universal apps directly from VS by switching platform to Windows Phone(universal) and choose Windows 8.1 Emulator. But it expects Emulators for Windows Phone 8.1 to be installed.
If didn't installed Emulators for Windows Phone 8.1 you can do so in Program and Features -> Visual Studio 2015 -> Change.
Thanks for upgrading to the RTM VS 2015. Unfortunately, you do require VS2013 for Windows 8 emulators to be installed. They aren't available on VS 2015 or there is no stand-alone installer for the emulators. But you should be able to deploy your Windows 8 application on Windows 8.1 emulators, if that helps.
Correct me if I'm wrong:
The Windows Phone 8.1 emulators provided by VS2015 are only good
for testing Universal Windows apps (APPX) and nothing else.
Windows Phone 8.1
legacy apps (XAP) can only be emulated by installing the Windows Phone 8.1 Updated Emulators separately.
You won' find this piece of information anywhere on the MS reference sites.

Installer files not working on Windows 8.1

My installer works fine with Windows 7 32Bit but if run on a Windows8 64 Computer I get an out of memory error during the installation process.
The Windows 7 and the Windows 8 output are created fine with Inno Setup 5.5.5
Sorry forgot to cancel this.
I discovered my brand new Windows 8.1 computer with 32GB of ram was locked to 4GB of useable ram. I was getting out of memory errors. I have reconfigured the computer and now all is well.

How to use SQLite Windows8.1 binary in a Windows8 app?

How can I use SQLite Windows8.1 version in my Windows8 app, so as to provide compatibility with both Window8 and Windows8.1 platforms? I tried referencing the new beta version of SQLite Windows8.1 in VS2012, but it would not accept the dll as valid dll/assembly?
Do I have to create 2 vesions of the app, for both Windows8 and Windows8.1?
A version of an app build for windows 8 will also work on windows 8.1 but a version build for windows 8.1 will not work on windows 8 (and this is independent of Sqlite).

MacBook Pro and ASP.NET applications

Is it ok to develop ASP.NET web applications on MacBook Pro ?
.NET is only available for Windows. There's the Mono project, which is not affiliated with Microsoft, which aims to create an open source .NET runtime and developer tools, usable on *NIX (including Mac OS X). If you want to develop .NET applications under Mac OS, this is your only choice.
Speaking of a MacBook though, you can install Windows on it using Boot Camp or run it in a virtual machine and develop in Visual Studio like on any other Windows box. And this is ok, I don't think anybody will confiscate your Mac for doing so.
If you have Windows running on the Mac then it is OK.
Another way is to use some .NET IDE for Mac (e.g. MonoDevelop)
New from Microsoft, IDE for Mac, Linux and Windows: https://code.visualstudio.com/Download
The best method to do that would be to install windows 10 with bootcamp and then install .NET . The steps involved are pretty straight forward. Just open bootcamp and create the partition and select the ISO of windows. Once installed, tap the options key on boot to boot to windows. If everything is smooth, you can continue the development, else, just open bootcamp again and delete the partition.
