can't download JalView

Jalview Discussion

Hi Sha, I just saw this appear in our moderator list, since your email included images which were too big to post to jalview-discuss.

Just to summarise:

You’re on windows 10. You had an issue with java, and after uninstalling/re-installing, Jalview didn’t work. Uninstall/re-install lead to a stacktrace in the flexera installer. It would be good to see that stack trace, in full (you should be able to copy/paste it out of the exception dialog box into notepad/etc).

Firstly - which version of Java did you (re) install ?

The remaining errors ('Error opening registry key ‘Software\JavaSoft\Java Runtime Environment’, ‘Error: could not find java.dll’, and ‘Error: could not find Java SE Runtime Environment’) all look like they are due to Jalview’s installer thinking there is a version of Java on the machine already, and trying to use that. You mentioned that you have java enabled in your browser - does that mean you can go to java.com and it reports that you do have java available ? If so then you didn’t really ininstall Java properly. Either way it looks like something is up with your machine’s registry re Java installation keys.

I’ve forward this to Ben Soares - our specialist on installing/running Jalview on windows. Hopefully he’ll be able to help you out - perhaps by working out how to force the InstallAnywhere Jalview installer to use its build in version of Java…

Over to you, Ben…

First I used to have JalView and it worked fine, but then I had to uninstall and reinstall my Java. Then JalView quit working and I uninstalled it and tried to re- install it. This is the error I was getting. ( I have Windows 10 on a Lenova computer and use chrome or firefox)

Then I decided to uninstall my Java and just reinstall Jalview that includes Java in the one step process, but the following are the errors I got with that. I have Java enabled in my browser.

After trying to install Jalview and Java and reinstall several times Friday, I finally gave up. When I got in this morning, I checked my Java installation (8+), it looked fine, and I tried again to install Jalview. It worked fine this time. I can’t explain it other than my computer needed to rest over the weekend. ??

Anyway all is working now.
Thanks,
Sha

Hi Sha,

After trying to install Jalview and Java and reinstall several times Friday, I finally gave up. When I got in this morning, I checked my Java installation (8+), it looked fine, and I tried again to install Jalview. It worked fine this time.

Sounds like a reboot (or something) has fixed up the dangling registry entries.

I can’t explain it other than my computer needed to rest over the weekend. ??

I’d stick with that explanation - it might be our most “popular” FAQ solution if we did put it on the website !

Glad things worked out in the end. We’re working on a new distribution/packaging model for Jalview - including a single bundled executable that doesn’t require an installer at all. Stay tuned !

Jim.
