I have a fresh install of windows and have tried every available version of PX1. After installing I attempt to open PX1 but it only appears in task manager briefly before disappearing and not opening at all. There also is no crash log folder in the program files folder. Anyone know how to fix this? 
 
Trying this with a 2080 ti FTW3

I have tried all this and it still doesn’t work. I do however have a 2080ti and a 1080 installed in the system so the 1080 being in the system may be the cause? But I have tried running PX1 with the 1080 removed from the system and it still will not open.

Only use the Newest version 0.3.9 with that FTW3 card 
 
MCU updater has issues with FTW3 cards for several people with the Older versions of X1 --- several had to RMA the card

Does PX1 fail to run from the Desktop shortcut, or with Windows if you set it to 'Start with OS' in the settings, or both?

Let me guess..You're running Windows 10 Pro?

A couple things.
 
See if there's been any Windows 10 Updates that may be causing it..Action Center (System Tray, near Clock) -> All settings -> Update & security -> Update history..Uninstall (if possible) any that coincide with the problem and then restart your PC.

Uninstall Precision XOC..Restart your PC..Delete the Precision XOC folder located in the Program Files (x86)\EVGA folder..Delete EVGAPrecisionX from the Task Scheduler Library if it exists..Restart your PC again..Install and set up Precision XOC again..Enable 'Start With OS' in the General Settings options (gear icon, bottom-right of Precision XOC)..I would do this first if you haven't already.
 
To open Task Scheduler, press the Windows + R keys to open Run, then type Taskschd.msc into the box, and then OK.

Roll from there.

 
Is this what I may need to do but with PX1 in place of XOC? (Found this in another thread where you mentioned 10 pro)

Thought so..I think it may be a permissions issue that has happened before to other people running Win10 Pro.
 
Right-click on the PX18.exe in the Program Files\EVGA\Precision X1 folder and go to the Properties, then the Security tab and make sure the user has permissions..Edit the permissions to give full control if not..See how that rolls.
 
I would disregard that post I made and you quoted above, for now..They're two different versions in different locations.

Unfortunately that did not fix the issue. I tried giving every group listed full permissions as well with no success.

You could try Revo Uninstaller (Free) to uninstall PX1..Use the Advanced Mode after uninstall completes to scan for and delete the leftover registry entries* and program files/folders that are found..Then restart your PC and install PX1 again.
 
Other than that, hmmm.
 
*WARNING!: Delete only the registry entries shown in bold text in Revo.

This did not work either. I also tried it with the permission changes you suggested earlier.

Also to note, on my windows install before this one, the first few PX1 versions that came out did not work either. However, one of them eventually worked briefly until I closed it and it would never open again.

Thanks for the help you’ve provided so far.

Maybe we'll get this figured out yet.
 
If the above suggestion don't work, set Windows to 'Show hidden files, folders, and drives' in the folder View options.

Open the user.cfg file (with Notepad) that's named and located similarly to mine in the C:\Users\Robert\AppData\Local\EVGA_Co.,_Ltd\PX18.exe_Url_o1iyvefks0podyj3z1ruu2zk5ljostmb\0.3.9.0 folder.

Under the <PX18.Properties.Settings> near the top, change both of the 'True' entries shown below to 'False' if they are not already..Close and save the changes..Then try opening PX1 again.
 
<setting name="General_StartMinimized" serializeAs="String">
                <value>True</value>
 
<setting name="IsOsd" serializeAs="String">
                <value>True</value>

Or, just delete the user.cfg file which will be recreated the next time PX1 runs.
 
I see that the user.cfg file remains after uninstalling PX1 (which has been an ongoing issue for many versions now) and even Revo won't recognize it..Having OSD enabled at PX1 startup has been known to be an issue and I suspect that's the problem.

That's all that's in the user.cfg file?..That's not cool at all.

I still think it's a permissions issue with Win10 Pro..Read a little farther down in this thread.

You may need to give the .cfg files write permission.

Here is a copy of my user.cfg file I put on my OneDrive page for you..You might try replacing yours with mine and set how it rolls..It's in a stock, unadulterated configuration from a clean install of PX1 v0.3.9 BETA with OSD and Start Minimized disabled.

So my config file already had full permissions and replacing my file with the one you provided didn't make it work either. I tried changing IsUpgradeRequired from false to true once again and upon running PX1 it changed it back to false. I wonder if my file was incomplete because the program never fully loaded. 
 
I've also now tried giving every folder/file in the EVGA PX1 install location and appdata files full permissions which doesn't seem to change anything either. 
 
On another note, I have also contacted EVGA support and linked this thread to them so hopefully I hear something from them as well.

We tried..Hope you get it figured out..Post back if you do..Good luck.

Will do! Although I feel like it is something that will have to be fixed in a future version of PX1 and not a setting on my end.. 

This is also happening to me. 
 
2080 Ti XC2 Ultra came in today so installed Precision X1 BETA 0.3.9 and it will not start up at all. I'm on Windows 10 update 1809
 
I do have the 2080 in the bottom PCI-E Slot on the mother board and GTX FE 1070 in the top PCI-E slot, if that matters.

Same problem..
I was reading a webpage and heard my rtx1070 xc ultra start throttling, and was like that's odd. So I tried to open X1 to look at the fan speeds and I can't open it.
I closed the webpage and the throttling stopped.
It was working just fine the other day, only reason I heard it was because I wasn't wearing my headphones. XC Ultra sure is a quiet card.
I did install a new driver from GF experience yesterday, is that the problem?

I have the same problem with PX1 on Windows 7 64 bit, all I get when I run the program is a hourglass for one second then there is a message stating that the program stopped working and windows is sending a report to Microsoft for them to look at. I've tried all versions down to 0.2.5 and no of them are working on my system. I have a EVGA 2070 gaming GPU.
