LiveCode 7 won't start after updating from 6.7

Post by tjo7777 » Thu Feb 19, 2015 10:11 pm

I had LiveCode 6.7 Community Edition installed on my Windows 7 computer. It was working fine, I built some android apps and .exe.

On two occasions I have tried to update to a more recent version, today I tried to update to 7.0.1 and 7.0.2.

However after uninstalling 6.7 and installing 7.0.x versions LiveCode will not seem to start. I can click on the desktop icon or on the LiveCode Community.exe found in C:\Program Files (x86)\RunRev\LiveCode Community 7.0.2 (rc 1), but nothing happens.

Any advice or suggestions on how to get a more recent version of LiveCode to run on my Windows 7 computer would be greatly appreciated.

Thanks in advance to anyone who can offer advice,

TJ.

Same here but for me it's an install from zero of version 7.0.1
then I have tried v 7.0.2 then 7.0.0 ... nothing.
I have a laptop Intel Core 2 duo with windows 8.1 64 bit.
On the same laptop Livecode works booting Ubuntu 14.10 64 bit.

Hi pigia,

Thanks for your post. Your post made me realize I could have included a bit more info about my set up. I have a core2duo processor, 4gb ram, windows 7 64bit.

I have tried uninstalling and reinstalling several times now, rebooting after uninstalls and after reinstalling, all without success. The one thing that does work is if I reinstall the old 6.7 version, however I would like to use a more current release.

My thinking at this point is that the uninstall must be leaving something behind, configuration files or possibily registry entries that cause the newer version to look for core components or resources in the wrong place. When time allows I will try to be uninstall and then look for and remove any remaining files or registry entries I can find. I can't think of anything else to try. Obviously it works for other people.

The one of thing I notice is we are both using 64bit windows. Are there any known issues with 64bit win7/8.1?

If anyone can offer more specific advice it would really be appreciated.

TJ.

I have solved the problem on my laptop tracing process "Livecode Community.exe" with Process Monitor from Sysinternals comparing output with the one coming from same program on my desktop Win 8.1 x64 succesfully running Livecode.
Here the problem was the spooler: I disabled it on my laptop for performance tuning (as I did with many other services...) since I don't need to print at all on it.
Give it a try:
start process monitor
go to Filter -> Filter (or CTRL+L)
add the condition: Process Name is LiveCode Community.exe
(you have to manually write the process name)
click ADD then OK
CTRL-X to clear display
Now, start Livecode. Go check process monitor, go to the end of output and then go up until you find the line of "thread exit" and check for the last thing done before that.
Hope it helps.

Thank you so much. I also had print spooler disabled. I enabled it and everything worked!

Also thanks for the tip about process monitor. I used it long ago, but never in the way you describe to trace the "thread exit". It's surprising that Windows doesn't offer a good way to do this, it would seem very useful for troubleshooting problems like this!

Thanks again,

TJ.,
