The latest version mLaser for Windows Computer is v2.4, normally, it won’t ask you to update if the version 2.4 is successfully installed.
On my Windows 7 computer, I installed the mLaser 2.4, when click on “Check for updates”, it shows the picture below:
You may totally uninstall the software and delete the previous installation package, then download and install mLaser 2.4 have a try.
For the resizing, actually, this is normal on mLaser software, it was written to automatically change the size of the image to a standard size in the program.
If you want to change the size of the image imported, you can double click on the image and input the size of it to the one you need.
