Installing version 5. As previous version, doesn’t recognize where to install. After I used advanced option, does nothing. I tried uninstalling previous version first, or not, neither works so far. I’m on trial version, maybe that’s why ? Thanks ---

Hi Aleksandar, > As previous version, doesn’t recognize where to install. > Which version of UE are you using? Is it a custom branch or an official released version from the Epic Launcher? > After I used advanced option, does nothing. > Where is it installed? After you use Advance option did you set the path to the destination of the Plugins folder in the location where your engine is installed? > I’m on trial version, maybe that’s why ? > Trial version has no limitation despite the 30 day license.

I’m using UE 4.26.2, official version, Vray for Unreal 43025. This version was installed and I tried both, installing on top of it, and with uninstalling this version and installing new one. Which way is correct ? Should I uninstall before installing new version ? Do I need to restart the machine ? Regarding plugin placement, yes, I had to point out which version to install, because neither version finds my UE installation. Not sure why, it’s installed in usual place on C drive. And yes, I’ve pointed the plugin directory correctly, since the 43025 version works. Thank you Aleksandar ---

Does the Advanced Settings page looks like this: [https://drive.google.com/uc?id=1JvbpkjDBM8xvO2\_cRLfafKV1L99SgqPw](https://drive.google.com/uc?id=1JvbpkjDBM8xvO2%5C_cRLfafKV1L99SgqPw) ?

Maybe something got mixed in your Windows registries. Best regards, Alexander ---

Hi Alexander, Yes, advance page looks like that, all the same, and I’ve chosen workstation, not standalone. Previous version work fine, this one doesn’t seem to want to install for some reason. I will check if I can find log file. Don’t know why would anything be wrong at registry, it’s fairly new installation, nothing crazy. Aleksandar ---

Hi Aleksandar, There is an install.log that is located in \*C:\Program Files\Chaos Group\V-Ray\Unreal\uninstall .\*Could you please send that so we can look at it? Best regards, Alexander ---

Hi Alexander, I couldn’t attach the file with extension log, so I renamed it install.txt. Please find it attached. I checked registry, inside it seems that UE engine paths are all with small letters. Like this: “C:\program files\epic games\ue\_4.26\engine\binaries” etc. Hope that helps. Thanks Al [install.txt](https://forums.chaos.com/uploads/short-url/wTEMLfjliNHSyFVg1I4M4cFDRKH.txt) (44.3 KB) ---

Ok, that explains why the autodetection failed for the installation. I sent you a personal message with a link to a nightly build. Have you tried with that build to see if the custom installation is successful? Best regards, Alexander ---

Is there any chance I can get hold of this nightly build? I too am having issues, with the exact same versions of Unreal Engine. I also do not have anything from Epic Games in my registry which is weird.. I’ve just installed the versions today ---
