Celestron Updates

[impactcrater]

Some will be familiar with the firmware updates known as CFM and coming as a zipped file which creates a JAR file from which you are supposed to be able to access the internet and connect to your scope and update it...it is generally a pain and I have told celestron it is awful...

that said , one of my laptops will open the JAR file and the other will not despite the newest version of java...

there may be a file association problem and windows 10 makes your choices very poor...

any ideas greatly appreciated

PS

I searched this item in the forums but could not find a reference to it.....

a jar file is just a zipped collection of folders & files, so try adding\changeing the file extension to ".zip" & see if it opens....
