the idea of making your usb stick a windows 7 installer doesn't involve lot of software. All you need is a bootable disc / image which you have. Following are the steps
1. backup usb stick (will be formatted in the due process)
2. clean usb stick and create primary partition and activate it -
a. open windows command prompt in administrator mode
b. drive/folder> diskpart <press enter>
c. DISKPART> LIST DISK <press enter>. Note down the disk number of the usb stick e.g.
Disk 1
d. DISKPART>
SELECT DISK 1
e. DISKPART>
CLEAN
f. DISKPART>
CREATE PARTITION PRIMARY
g. DISKPART>
SELECT PARTITION 1
h. DISKPART>
ACTIVE
i. DISKPART>
FORMAT FS=NTFS
j. DISKPART>
ASSIGN
k. DISKPART>
EXIT
(you are not yet done with the command prompt)
Since you have ISO image, either you need a virtual drive to insert the image, if you have one, good enough.. otherwise try Daemon Tools, or extract the iso contents in a folder.
Assuming your virtual drive is on with the iso image inserted, i'll considering following;
A. your drive letter for USB STICK is E:
B. your drive letter for virtual drive with inserted iso image is F:
3. drive/folder> f: cd BOOT
4. f:\BOOT\>
BOOTSECT.EXE /NT60 E:
this will write the bootsector information in your usb stick
5. copy all the contents from the virtual drive or extracted image folder onto your usb stick.. and voila.. you are good to go 😀
