Solved: How to open Celestron Firmware Manager when the Jar file that was unzipped from the download can't be made executable I.E. into an exe

Recommended Posts

Posted (edited)

Hello there,

I told you it wouldn't be long before I started asking for help! ;)

I can download CFM from Celestron's support page. I download the zipped file, extract the contents but that's as far as I can get. 

The file in the unzipped file shows as a 'Jar' file instead of an exe. That naugghty little jar justs sits there and will not dance for me. 

I am running Windows 10. I have latest version of Java installed. I have tried turning around 3 times with one hand on my head and one on my tummy. No luck.

I am neuro A typical, for the record, so that accounts for why I absolutely MUST know how to (please) open this file even though the odds are my kit is up to date. 

Seriously, this is driving me nuts. I found stargazerslounge via my searches in trying to solve this problem and I thought to myself what a nice vibe this ite has. so I joined. 

Any help / advice / chocolate (milk or dark) , money (PP or cash ;) ) all very gratfefully and cheek kissingly received.

You need to run the executable file from within its (extracted) directory. 

Sorry just seen that you have no executable file.

Extract the zip to a folder - then right click the jar and run as administrator... I'll check on my laptop in a min😃

You can check the firmware version in your handset and see if it is the latest available. If it is the latest version, you don't need to do anything.

Even if it isn't the latest version you probably don't need to do anything.

Old engineer's saying: if it ain't broke, don't try to fix it.

There are posts from people in this forum who have updated  firmware and made things worse.

Thanks. I reinstalled Java but no luck. Strang thing is, some peeps using Windows 10 have no issue opening Jar files, some, like me, do. And that seemingly random variability is extremely annoying.

How olds the scope out of interest, theres the "firmware" manager and then theres "ye olde firmware" manager.

Don't panic anyway, you may of hit the motherload:  https://www.nexstarsite.com/Firmware.htm

Thanks. The tube and mount are brand new, so odds are they won't need an update. But I was so looking forward to plugging it all in and checking for updates. I love stuff like that WHEN IT WORKS but get very irritated and sad when it doesn't. It just drives me nuts not knowing why I (and others) can't make jar files executable. My instinct is is it may be something to do a matrix between the security software and Java. Security software / anti vrus issues might accaount for why some Windows 10 peeps have this problem and others don't.

is there another Pc you can try it on?

Obviously always nice to have the latest version, but most of the updates as far as I understand have been about fixing old bugs, I doubt your missing out.

Have you tried right clicking on the .jar file and choosing 'open with'? You then need to choose the java platform binary (java.exe), which if it doesn't show can be found in c:\program files(x86)\java\jre1.?????\bin   (where??? is whatever version of java you have installed. This is the 32bit version of java - if you have a 64 bit version installed you will find it in c\Program Files\java\jre1?????\bin

If this works you can tick the box that says 'always use this app to open .jar files'

Seems like a lot of Windows 10 user have your problem from a quick search on cloudy nights site.

You might need to try jarfix:

Hi & thank you for taking the time to help me. I didn't try your suggestion - I tried 'Jarfix' first - but I suspect that your method would have achieved the same success. I had tried right clicking and doing 'open with' but it seems unless one has the fix provided by Jarfix, the option to open with Java is never there. The best option Windows 10 gave me was to try Firefox....................... Thank again. :)

      Hi everyone,
      My other half bought me (us) a Celestron 130 for my birthday recently.
      I have watched tutorials and done a lot of reading about collimating and various other tips since alongside several hours peering through the telescope.
      I can achieve a very crisp image of the moon which is awesome. However, trying to get a decent focus on Mars/Jupiter Saturn is proving very frustrating. The only non-blurred image of any of them is a single white-point, non dissimilar to what I can see via the naked eye. 
      i’ve tried both the 20mm & 10mm lenses and adjusted the focus in and out all the way.
       
      Any advice would be gratefully received.
      thank you, in advance.

      I have just encountered an error message which says "NO RESPONSE 16" when I power up my 130slt. Has anyone else experienced this issue?

      Hi,
      I am hoping someone here may be able to offer some help or advice. I have submitted a support ticket with Celestron but I am still waiting for a reply and would really like to get this working ready for the next clear sky!
      I recently brought a starsense but have not been able to use it because it comes up with the following errors,
      Err: Model Num
      The telescope model could not be read and initialization cannot proceed.
      Critical error!
      File: ..\source\mo
      Line: 1468
      An unexpected error occurred that may cause the HC to not opperate normally.
      When updating the controller and camera it finishes succesfully but when I check for new updates it proceeds to install the same one again and again.
      I can still control the mount and I think the camera tried to do an alignment in my room.
      I have a Celestron Nexstar 6SE.
      Thanks
      Adz

      Hi, 
      Just thought I'd share this in case you haven't seen it already. A recent (September 2020) article added to the Celestron 'Knowledge Base' on collimating SCTs.
      I don't claim to have seen all articles on collimation, but this is defs one of the best that I have seen.

      I have the aforementioned telescope but not used it in several years. It's just been sat, quietly out of the way in a small cupboard (dry, dark, nothing amazing) but not stored in it's box as perhaps it could have been. Nonetheless, I went to take it out as a friend had asked me to take it to his for an evening's viewing pleasure. I tried the batteries I'd just bought (16xrechargables) but was unable to get any signs of life. Between myself and a friend who's somewhat more conversant with electricity than myself, we discovered so far that there's no signs anywhere of life from it - but we're not (as yet) sure whether it's a poor connection from the battery compartment or the switch. We do know the batteries are good. 
      Any advice on narrowing down causes, please?
