It's not possible to change the currency of the application since it's used for Indian audits. There is also no point in using US Dollars or Pounds. The software was created for Indian industries and market without any possibility to change to Dollars or Pounds. I have installed this version and currency is not available for changing.
I would recommend checking for more information about the software using the PDF file available for this procedure: http://www.mca.gov.in/XBRL/pdf/Saltlake_Infosolutions_Pvt_Ltd.pdf
Also, you may contact the developer and ask him about the currency change or if it's even possible to do it. Use the following email address: contact@saltlakesoft.com
For the file above, you'll need a compatible PDF reader as well.
