Windows 10: Program runs twice, and hence crashes

Hello. I am new so if i say anything wrong, please forgive

I have a barcode printing program called qz tray.

It refuses to launch. I have windows 10 running on a microsoft surface pro 3 tablet. When i try to start it, nothing happens. When i look at the program's diagnostics debugger output, it says another instance of rhe program is running already, and closes. I have only one account on my tablet. What should i do to fix this? I have uninstalled and reinstalled it, as well as java version 8 many times, to no avail. Below is rhe message in the debugger. Can you make sense of it and help me fix it? Help. I will be forever grateful. :.

Running a program twice?

the point is, you cant run steam twice in the same OS.

even if he did run it in a VMware, or on another physical machine - he doesnt get what he wants out of it (access to both friends lists in the steam overlay, or whatever he actually wants)

 

Running a program twice?

I have been wondering this for a long time. is it possible to run a program twice at the same time. Like say im running steam and i wanted to log into another account but stay logged into my current one, is there a way to run steam two times at the same time?

 

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?
