The wallet strarts but doesnt create that file Mousecoin.conf ?
Ok when you first start mice wallet some files are created in C:>users>name(or admin)>AppData>Roaming scroll through this roaming folder until you find a folder called Mousecoin and double click.
If you can not find the AppData folder then you need to click on the view tab above file explorer and put a check mark on the box that says hidden files. Now you can find the AppData folder.
Once you are in the Mousecoin folder create a new text file from notepad and paste in the following info:
listen=1
server=1
maxconnections=500
rpcuser=yourusername
rpcpassword=frAqBc8Wsa1xVPfvJcrgRYwTiiu
port=10092
rpcport=10091
rpcconnect=127.0.0.1
addnode=199.26.184.214:10092
addnode=134.255.220.128:10092
addnode=134.255.227.59:10092
addnode=149.56.154.75:10092
addnode=163.172.189.215:10092
addnode=172.111.200.54:10092
addnode=176.212.245.226:10092
addnode=185.2.100.251:10092
addnode=198.187.28.18:10092
addnode=31.214.149.227:10092
addnode=5.164.7.163:10092
After that comes the tricky part, with notepad still open click on file navigate to save as and select it. Rename the new text as Mousecoin.conf and the immediately under file name go to save as type. The drop down box will give you 2 options select the second which says all files then hit save and now you are all done.
If you don't select all files then you end up with something that looks like this Mousecoin.conf.txt If you did it right then the file is without the .txt file type and looks like Mousecoin.conf as conf is now the file type. The above conf example came directly from the wallet with the exception of the addnodes that I had found from novaexchange
