Currency converter exercise problem

Hi,
I have added “Use Excel file” and “Read csv” and configured them as specified in the video. After pressing the Run button the system gave the message (I have translated it from Russian):
Version:1.0 StartHTML:000000258 EndHTML:000005879 StartFragment:000005261 EndFragment:000005818 StartSelection:000005261 EndSelection:000005818 SourceURL:file:///C:/Users/Владимир/Documents/UiPath/CurrencyConverter/RuntimeExecutionError.html Runtime execution error body { font-family: Segoe UI; margin: 0; border-top: 1px solid #d9d9d9; } img#warning { float: left; width: 28pt; } div#header { min-height: 80pt; max-height: 290pt; margin: 16pt; margin-top: 8pt; } p { margin: 0pt; } div.action_info { overflow: hidden; border-top: 1px solid #d9d9d9; width: 100%; position:absolute; bottom:0; background-color: #f5f5f5; } p.action_info { float: left; margin: 8pt; margin-left: 44pt; } .btn { cursor:pointer; display: inline-block; font-weight: 400; color: #242424; background-color: #e8e8e8; border-color: #c5c5c5; text-align: center; vertical-align: middle; -webkit-user-select: none; -moz-user-select: none; -ms-user-select: none; user-select: none; border: 1px solid; padding: 2pt; line-height: 1.5; transition: color .15s ease-in-out,background-color .15s ease-in-out,border-color .15s ease-in-out,box-shadow .15s ease-in-out; } .btn-primary { border-color: #0073ce; } .img-resize{ height: 75px; width: 210px; overflow: hidden; border: 1px solid #c5c5c5; } .img-resize img{ max-width: 100%; object-fit: cover; } #problem-element-image-container { align-items: center; display: flex; } #action_info_text{ overflow: hidden; position:absolute; bottom:44pt; left: 16pt; color: #707070; background-color: #FFF; } #buttons_master_container{ width: 80%; float:right; margin: 8pt; margin-right: 12pt; } div.ImageClear{ clear:both; } #appImagesContainer{ display: flex; } div#buttons_container { clear: both; } #buttons_container input { float: right; margin-left: 8pt; padding-left: 5px; padding-right: 5px; } div#arrow-container { width: 48px; } div.center-align { position: relative; } div.center-align img{ position: absolute; top: 0; bottom: 0; margin: auto; left: 0; right: 0; } .modal-image { border-radius: 5px; cursor: pointer; transition: 0.3s; } .modal-image:hover {opacity: 0.7;} .modal { display: none; position: fixed; z-index: 1; padding-top: 100px; left: 0; top: 0; width: 100%; height: 100%; overflow: auto; background-color: rgb(0,0,0); background-color: rgba(0,0,0,0.9); } .modal-content { margin: auto; display: block; max-width: 700px; } #caption { margin: auto; display: block; width: 80%; max-width: 700px; text-align: center; color: #ccc; padding: 10px 0; height: 150px; } .modal-content, #caption { animation-name: zoom; animation-duration: 0.6s; } @keyframes zoom { from {transform:scale(0)} to {transform:scale(1)} } .close { position: absolute; top: 15px; right: 35px; color: #f1f1f1; font-size: 40px; font-weight: bold; transition: 0.3s; } .close:hover, .close:focus { color: #bbb; text-decoration: none; cursor: pointer; } @media only screen and (max-width: 700px){ .modal-content { width: 100%; } } #SkipIterationContainer { /* display: none; / display: none; } #ExcelCardDetailsContainer { / display: none; / [EXCEL_CONTAINER_VIS_PLACEHOLDER] } #OutlookCardDetailsContainer { / display: none; / display: none; } #ApplicationCardOnlyDetailsContainer { / display: none; / display: none; } #ApplicationCardWithElementDetailsContainer { / display: none; / display: none; } #ErrorPathContainer { / display: none; */ [ERRORPATH_CONTAINER_VIS_PLACEHOLDER] } .scrollable { overflow-y: auto; } .unscrollable { overflow: hidden; } #problem-desc { white-space: pre; }

It is not to bring COM-object of type “Microsoft.Office.Interop.Excel.ApplicationClass” to the interface type “Microsoft.Office.Interop.Excel._Application”. Error operation completion, as the call of QueryInterface COM-component for the interface with IID “{000208D5-0000-0000-C000-000000000046}” returned the following error: Interface is not registered (Exception from HRESULT: 0x80040155)

After that I have removed MS Office 365 from my computer, rebooted it and installed MS Office 365 from my page on the office.com site.
The error has not disappeared.
How can I fix it?
Best regards,
Vladimir

Is it licenced MS office software? If not try to activate the account.

Yes. I have licensed MS office. I have checked through regedit that correct path is indicated in the floder 0 to Excel.exe. I also see that when I start Excel.exe it loads UiPath.Inegration.ExcelAddin. But as I have mentioned in the first message the problem remains. But in the log of Excel Addin Install it also specify the issue. (while StudioX said that ExcelAddin was added sucessfully).
