Dear Mr Kostov
I have two useful suggestions for You.
Do not use Jaws with live projects, as Jaws have been developed for standard installations, integrating videointercept is not easy and it will be may be very complex, as universal video driver can make some hydden complex issues while working with Jaws.
It is even not easy to synchronize Jaws startup and sound driver and sound service, remember on The systems with 512 MB of RAM.
Try to use NVDA with Win7 PE NVDA2, solution will ve very probably available to fix memory related problems.
It is not good idea to work with Jaws in live mode of Windows operating system, as there is problem with some specific Jaws features. How You will use Jaws specific features related to Powerpoint? Or Microsoft Word?
Will You try to use Microsoft Word in live mode?
I think, that NVDA is ideal screen reader for live projects, as integrated programmers techniques are fully compatible with live projects design, there is no ned to start The reverse engineer process of analysing registry values of standard Windows installation, which registry keys have been created while installing Jaws, video intercept of this product, ETC.
I have even found out, that there can become very complex programmers issues while triing to use some complex programs in live mode.
For example, some Borland delphi compiled .exe programs can not be used in live projects mode while running projects based on WIndows PE no matter, if on version 1.0, so installation source were Windows Xp or Windows PE 3.0, installation source have been used as Windows 7.
For example, hddregenerator .exe GUI application can not be used, there is some complex issue with access violation address.
And Jaws is using much more complex dlls and activex controls.
You would end with AN live project, which would had to be used with setpagefile.exe to use Windows swap file of internal harddisk IDE or SATA compatible.
So my suggestions are:
1. use The latest MULTIPE from Peter Schlang, use it with NVDA, You must locate The mynvda script, use radio button portable NVDA from path, browse to The folder with portable NVDA installation.
Use The Windows XP installation source, and aspecially, activate The activate NVDA checkbox as a first checkable object after running winbuilder.exe
After extracting Multipe archive.
Multipe is supporting NVDA, but You must press TAB and Space key after booting resulted .iso to confirm, that NVDA should be automatically loaded.
USB headsets or USB sound cart to work ith it.
Kindand soft Mr Amalux have been created LX project, which is supporting Windows XP as source.
I Am recommending You to use XP live projects, as there is very little memory consumption while working with The project.
Using for example antivirus tools is allocating many MB of RAM, clamwin portable will allocate for example more than 50 MB, so it is not always easy to use live projects successfully with NVDA, as NVDA will allocate minimum of 32 MB.
There is no other free international alternative, which would allocate less memory.
Even those issues are not good, The fact is, that using live CDS based on Windows preinstalled environment is much universal way for visually impaired users to access The compromited systems.
Eventhough there are articles on The Internet, which will allow You to create universal XP or even Windows 7 bootable USB sticks, Windows OS will run not in live mode, but as a full featured OS, there is licensing issue and memory allocation issue.
Live projects are The fastest possible way to boot this kind of repair environment, boot data can not be randomly corrupted so easy.
So use Multipe firstly, then try to use Windows 7 based project, Windows 8 would use much more RAM, because newer version of WWindows will use more memory and XP is for us The fastest and memory efficient way to use repair environment.
Linux live CDS will never allow You to check The NTFS file system or even modiffy registry safely.
