Error while installign AIR Application (invalid package signature errorID=5022)

Question

Hi All,
I am new to Adobe AIR and facing error while Installing AIR application. This specially happens when in include a folder named "htmls" in the assets directory in my project.
This folder have lots of html files and others folders. These file names have some special characters as well like ". & - _".
However I can install the Application when I exclude this folder and everything works fine. Not able to find out the exact problem.
Looking forward for help !!
Log contents:

.airinstall
App installer failed; exit code 7
begin quitting

You may have found a bug in the AIR installer or packager. Given that the signature is an XML file, the "&" character seems the most likely culprit.
The only short-term workaround is to identify which characters cause the problem and avoid using it.
You should avoid the following characters in any case, since these cannot be used in file names on all platforms:
Character            Hexcode
various     0x00 - x1F
*           x2A
"           x22
:           x3A
>           x3C
<           x3E
?           x3F
\           x5C
|           x7C
