Ubuntu 11.04 can't set execute permission for Windows exe's

Please note Ubuntu 11.04 is an unstable release NOT SUGGESTED for every day use it will be released as stable in April 2011

I thought I was on the latest stable release. How do I revert?

Please install wine package and try to open with wine

You can use this release i have it on 2 pc but you can have trouble on some new functionality.
So please tell me what are the most used apps you using on Ubuntu...?

IrfanView
Notepad++
GoldenEagle FlightPrep
AZZ Cardfile

So I should remove and re-install Wine or just re-install?
Can Wine re-set the execute bit?
In the past I had to set it manually.

Oddly, Notewhen from PCMag still works.

In my experience, downgrading an entire system isn't really doable, so I'd recommend backing everything up (unless you have clever partitioning that negates that) and reinstalling 10.10.

I don't think this is a Wine problem. It's a permissions problem.

Some of my old Windows apps work under Wine and two important ones balk at being non-executable.
IrfanView and FlightPrep.

Here is what happens when I try to change the permissions: (note that it says it worked, but it didn't)

root@howard-ubuntu:/media/Windows/Program Files (x86)/IrfanView# chmod -v +x+x+x+x i_view32.exe
mode of `i_view32.exe' changed to 0711 (rwx--x--x)
root@howard-ubuntu:/media/Windows/Program Files (x86)/IrfanView# ls -l
total 897

This could be an issue with the mounting of the device.
Could you post the output of "mount"?

I was able to run each of those applications from the command line in Terminal.
wine pathname filename
This did not install them properly in wine but it did run them OK, permissions notwithstanding.
So I build menu items that used the above syntax rather than trying to run them from inside the wine menu.
That worked.

Thanks, everyone for the help.
This is a workaround, but an acceptable one.

It seems to me that if you are "root" you should be able to make anything executable. Apparently, the security policy does not think so!

They on an ntfs partition?
I can't get things to execute from my external harddrive

All the Windows applications are on the Windows partition which is NTFS.
Since I was able to set the execute bit in previous versions, this is something
that changed with the new version.

To repeat, even though I cannot set the execute bit, Wine can run these applications.
But, I have to use this syntax:
Wine path/file where the path begins /media/Windows...

This works OK, so my immediate problem is solved by work-around.
I still think that as administrator or root I should be able to set that bit.

leighman, try installing ntfs-config and running it. It should allow you to change the read/write settings for your drive.

CDS,
This is very odd. I was able to write to that partition before. However, I did as you suggested and now the execute bit is checked.
The ntfs-config program does not explicitly mention the execute permission.
Strange.
But, THANKS!

I was able to Install Windows Applications from my pen-drive. Its a FAT-32 file-system.
Every time I check "allow execution of this file" In the Properties=> Permissions menu... Its gets Unchecked Automatically, Hence Installation Fails..
