When trying to file the CS01 with Companies House you receive the error message
“Element ConfirmationStatement is invalid
Line 36: The ‘http://xmlgw.companieshouse.gov.uk:ConfirmationStatement’ element is not declared.”
A hotfix has been released to resolve this issue and the service pack updated to include the changes.
This hotfix is compatible with the Spring Release Service Pack v26.1.10.61
| If you are on v26.1.10.640 or 26.1.10.60 | Update to 26.1.10.61(q) which can be found on our downloads page AS Downloads | IRIS Accountancy Suite Support | IRIS |
| If you are on 26.1.10.61 | Download and apply the hotfix to your full install and to any Local Programs Only installs. Installer IRIS 26.1.13 Hotfix Payload IRIS 26.1.13 Hotfix |
Hotfixes come in two formats, an installer and a payload.
The installer format can be downloaded and applied to IRIS installs like an update.
The payload format is a .zip archive that must be extracted and you then copy/cut & paste the files into your IRIS Installation locations.
The payload can replace the existing versions of the files or you can rename the existing files prior to pasting the hotfix payload into the directory.
Both formats need to be applied to your full install of IRIS, and any Local Programs Only (LPO) installs you may have deployed.
If you right click on the IRIS desktop shortcut and open file location it should take you to the relevant location for your install, with workstation (WSS) installs taking you through the main install location.
