Unity (5.6.0b11) il2cpp.exe did not run properly!

[roka]

Hello,

I have downloaded the version 5.6.0b11 beta of unity and when i try to build a new project with an empty scene, i get the following error. If someone know the solution ^^

• It can’t be a Facebook problem because with or without Facebook platform, i get the same error.
• I have already try “run as administrator”
• I have already try to change .net 2.0 subset to .net 2.0, same result.
• I’m on windows 7 64 bit.

Does it make any difference if your project is in drive c: ?

I will try to install unity in my drive C to see if it make a difference and i will post the result when done.

Still not working if unity is installed on my main drive and the project on my main drive :

[Marco-Trivellato]

do previous versions of Unity work for you?

[roka]

No problem on the 5.5.2f1

[roka]

Did you get any other infos?

Thank you.

[Michelangelo97]

Same problem it works for previous versions but not with 5.6.0f3

[alpha_rat]

I have a similar problem here, would be interested in a solution to this

[albertojunior84]

same here… was normal at other version, since the update (or should I say duplicated file?) my unity and projects are a completely mess, can´t build for webgl anymore. really unhappy with unity.

[Bbulle]

same here… I’m using 5.6.2f1

[Kingtem]

I’ve got the same problem, any news about it?
5.6.2f1

[roka]

Update your windows (windows update).

[Marco-Trivellato]

please let us know if installing Visual C++ Redistributable for Visual Studio 2015 solves the problem.

[DanJacksonALSC]

@Marco-Trivellato

please let us know if installing Visual C++ Redistributable for Visual Studio 2015 solves the problem.

This worked for me.

[JesseMartin]

I have the same issue on 2017.1

I’ve confirmed that I do have Visual C++ for studio 2015 installed on my computer (version 14.0.24212.0)

[Marco-Trivellato]

@DanJacksonALSC

This worked for me.

Good to hear. By the way, which version of Unity are you using?

[Marco-Trivellato]

@JesseMartin

I have the same issue on 2017.1

I’ve confirmed that I do have Visual C++ for studio 2015 installed on my computer (version 14.0.24212.0)

It might be a different issue then. Could you please attach the entire log?

[DarkMasster]

I have the same issue on 2017.1

I have 4 errors total, so I’ve pasted them all into one .txt file, each error seperated by a series of dashes ------
