Hi,
My university provides us with a very large (unlimited?) network drive to store our data. When running the PA platform from this drive, I get an 'invalid float operation' error. I know this error is listed as an unconfirmed bug. Therefore I wanted to confirm it as this bug seems to have been around for a long time.
Cheers.

If your network drive reports an invalid amount of free space (infinity), it'll crash the platform. We'll have to provide a workaround in the next release for you.
Sometimes, the impossible can become possible, if you're awesome!
I have the same problem at work. I haven't got "infinity" free space, and I thought the problem is the UNC, but... perhaps the the start menu of the platform is not able to manage the amount of free space...
Thanks for fixing it in next release.
Yes. It would be great to have a fix. Thanks & cheers.
One last question, did you try the current beta?
Sometimes, the impossible can become possible, if you're awesome!
Yes. That gave the same error.
I have the same issues. Has this been seen with very large drive sizes?
It is due to extremely large drive sizes that overload the size calculation. I'm not sure of the actual size limit, but know it works fine on 2TB drives. What size drive are you encountering the error on?

I've added it to the confirmed issues list: https://portableapps.com/node/28593
If anyone can determine the cutoff, I'll add that info. I'm working on switching the datatypes for Beta 3 which should fix this.

Ok, I figured out that it's an issue anytime it's run from a network drive that's not mapped to a drive letter regardless of the free space left. So, if you map a letter and run it from that mapped letter, that solves it.
I also worked out a solution so it can run from an unmapped network drive without causing the error and it's in the 12.0 Beta 3 internal build that will be released soon. The platform bugtracker topic has been updated to reflect this as well.

Hi everybody,
I also had the 'invalid float operation' issue when running PortableApps.com Platform 11.2 under Knoppix 7.2.0 using Wine 1.5.10-69. I couldn't get to the main menu and only right-click menu was accessible.
What I did to fix the problem? I started my 'winecfg', then went to 'Drives' -> Add -> Select Drive Letter. Then I selected the new drive, clicked on 'Show Advanced', selected Type 'Local Hard disk' and the most important - selected the Linux path to my external hard drive (my PAP is located there) - '/media/sdb1/' in my case. That's all! After that the 'invalid float operation' message disappeared, main menu is now accessible and free space is reported correctly.
I hope that this could be helpful to other people using PAP under Linux.
