Q)How can i upgrade the syncfusion to use the latest version of syncfusion? I am little doubtful to download which suite to use for this purpose. Can anyone please let me know how can i update the syncfusion in my project?

A)We have a project migration tool in our latest version( which is used to migrate project from one version to another version. Please download our latest version( to upgrade your projects to the latest version.

Please find the project Migration tool from the below location:

Start->All programs->Syncfusion->Essential studio>Tools->Project Migration-> Syncfusion Project Migration


You can find the utility from the below installed location.

{Installed location}\ Syncfusion\Essential Studio\ {Essential Studio version}\Utilities\Project Migration\ProjectMigrationWindows.exe

For ex:

C:\Program Files\Syncfusion\Essential Studio\\Utilities\ProjectMigration\ProjectMigrationWindows.exe

If you want to manually upgrade project from one version to another version, then please follow the below KB article.


Please let us know if you have any queries.

Thanks for your reply.

The current version that we are using for our project is 6.303.0.30
I have downloaded latest version of syncfusion and installed in the location C:\Program Files\Syncfusion\Essential Studio\

I could see some dll's
C:\Program Files\Syncfusion\Essential Studio\\Assemblies\3.5
in the specified folder. I have copied and replaced the old version with the new version.

After this, i got some errors in my methods.
Please find my sample code below:

protected virtual void addTable(IWTable table)
if (table != null)

foreach (WTableRow row in table.Rows)

foreach (WTableCell cell in row.Cells)

for (int i = 0; i < cell.Count; i++)
object foo = cell[i];
IWParagraphCollection paragraphs = cell[i] as IWParagraphCollection;
IWParagraph paragraph = cell[i] as IWParagraph;
WTable subTable = cell[i] as WTable;
if (paragraphs != null)
if (paragraph != null)
else if (subTable != null)




I am getting compilation error here in this line

for (int i = 0; i < cell.Count; i++)

I have tried using ProjecMigrationTool as well. There's something called Essential Studio version. as my current version is 6.303.0.30, i gave that in the textbox field, then its giving an error besides the textbox -> *Ex.

Please let me know if you need more clarifications on this.

I have fixed the error and is working fine now. But one my issue with the word file is not yet resolved. Resume Created with MS Word for Mac Cannot be Parsed, its giving error "Stream position is too big."

I am getting this error when i try to open the document.

var document = new WordDocument();
document.Open(wordFile, FormatType.Doc);//it breaks here.

What is saw is that properties are getting changed. I have attached the screen shot of both file properties. Please note that i have latest dll's. Please have a look at this and let me know your comments on this.

Hi Nimesh,

Thank you for your update.

We are able to reproduce the mentioned "Stream position is too big" in the provided template document (OfferLetterTemplate(1).doc). We have tried resaving the template document using MS Word MAC version 2008 and not able reproduce the mentioned issue with resaved document. We suspect the template document may be created using MS Word version previous to Word 97. For further reference regarding compatibility of DocIO, please refer our UG documentation form the following link.

UG Documentation link:

For your reference we have attached the document resaved using MS Word MAC version 2008. Please do find the resaved document from the following link.

Document link:

Could you please provide us with the MS Word MAC version in which the template document was created for further analysis? Could you please report this issue through Direct Trac Developer Support System https://www.syncfusion.com/account/login?ReturnUrl=%2fsupport%2fdirecttrac%2fincidents because you can take the advantage of the expertise of a dedicated support engineer and a guaranteed response time and we hope you will take advantage of this system as well. If you have already reported, please ignore this.

Please let us know if you have any other questions.
