Launcher Help

[DocileDragon]

Good evening. I am interested on playing on the Dungeons, Dragons, and Space Shuttles server, but whenever I try to launch the pack, I get this error (and I apologize if I didn't do this correctly; I'm not sure what I'm supposed to do...):

java.io.IOException: Cannot run program "C:\Users\That-\AppData\Roaming\java" (in directory "C:\Users\That-\OneDrive\Documents\CraftersLand Launcher\instances\DungeonsDragonsSpaceShuttles\minecraft"): CreateProcess error=5, Access is denied

Any help would be greatly appreciated. Thank you!

 I believe the latest version for DDSS is 8.0_R1 if you would rather use a different launcher.

Okay . there seems to be a folder permissions issue.  I would open up the folder "C:\Users\That-\OneDrive\Documents\CraftersLand Launcher" and right click on the "instances" folder and go to properties and check the folder security.  make sure its not Write Protected, and if its not, what i do because windows folder security aggravates me is, add a new "group or user" called "everyone" and then give it full access. that will be just for that folder "instances" and any folder inside it.  that gives java the ability to access it in the easiest way lol  but i urge you go read something like this to learn more about it.

@Nikkinz Thank you for that; I'm making progress with what OTwitch suggested. If I don't get anywhere with that, I will try it out.

@OTwitch Ok, I got past the "Access is denied" part, but if it's not one thing...

This is what appeared in the launcher log when I tried to launch DDSS:

The game is running. Please wait.
Invalid maximum heap size: -Xmx4096M
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Process ended with code: 1

Make sure that you have Java 8 and its 64 bit installed. If so uninstall and reinstall it.. Also make sure you have enough ram allocated to DDSS 8-10Gb. Hope this helps!

 

[OTwitch]

okay how much total system memory do you have ?  you really need 6 gigs + for ddss and 3 gigs for windows so 10 gigs or more total system memory

Sorry for the late reply, crazy work schedule. I have 16GB of RAM. I have Java 8 64 bit. I just don't know how I'm supposed to allocate more memory to the "heap size?" Under "Options," the maximum memory set is 4096MB. Does this count for the "heap size?" Or am I just dumb and missing something really simple? Because that's happened before...

[OTwitch]

in the options for the ddss pack in the craftersland launcher make sure permgen has 256MB set and make sure min memory is at least 3000mb and max is  (mine is set to 9000mb ) .

[DocileDragon]

@OTwitch I set everything exactly like you said, and it's still giving me the "invalid maximum heap size" error.

Minimum memory: 3,000MB

Maximum memory: 9,000MB

PermGen: 256MB

I even tried setting max memory to 12,000mb just to see if that would make any kind of difference; no luck. Still get the same error.

Additionally, I appreciate both you and Nikkinz taking the time to help me. Thank you.

You don't have java8 64-bit installed. Or if you do, you also have the 32-bit still installed and that is taking priority. Best to uninstall all of them and install the correct 64-bit java.

@Ness27 That did it! Thank you so much! Now I just gotta hope that my processor can handle all this. So far so good though. Again, thank you everyone for your help!
